Smart systems technologies are evolving towards ever increasing functionality and miniaturisation through the heterogeneous integration of separate components. The ideal integration requires precision placement of multiple types of devices on a substrate to allow their inter-connection. We propose to solve this integration challenge through an exciting new technique called micro-Transfer-Printing (TP) where the essential materials or devices, with thicknesses of a few microns, are separated from their native substrates and are transferred in parallel to the new platform according to the desired positioning while achieving micron-scale placement accuracy. Sequential application of the process enables different components of different functionality to be manipulated in a highly flexible and programmable way making best use of the materials. The TOP HIT project will aggressively develop and validate the TP technology by integrating electronics and photonics components for the magnetic and communication industries. These serve as examples for the broad capability of the technology which is compatible with low-cost manufacturing. We will develop On Head Microelectronics for data storage smart systems through the embedded integration of custom electronic circuits directly into the magnetic read-head. We will demonstrate TP as a scalable method for the integration of compound semiconductor based elements (lasers, detectors) with silicon photonics platforms demonstrating both a compact receiver circuit and a transceiver. The partners in the TOP HIT consortium include international companies with extensive manufacturing capabilities, an SME, and two research institutes. The output of this project will help establish TP as a mainstream technology for heterogeneous integration, enabling manufacturing to be carried out in Europe through sales of equipment and through foundry services. New more efficient smart products will emerge from the research carried out here.

The aim of the proposed research is to develop opto-nano-magnetism as a novel approach for future magnetic recording and information processing technology at the junction of coherent nonlinear optics, nanophotonics and magnetism. In particular, we are aiming to investigate effects of light on magnetic order at the nanoscale, to obtain highly efficient and ultrafast (10-12 seconds and faster) optical control of nanomagnets and thus initiate a development of novel technology for unprecedented fast (THz) magnetic recording and information processing, including spintronics. To this aim we have formed a multi-disciplinary consortium of academic and industrial partners with complementary expertise in coherent nonlinear magneto-optics and ultrafast magnetization dynamics, spatially and time resolved magnetooptics, nanophotonics and X-ray nanoprobing of magnetism, atomistic simulations of subpicosecond magnetization dynamics for strongly nonequilibrium ensembles of spins, technology of magnetic nanostructures and their applications in spintronics. The project is directly relevant to NMP-2007-2.2-2 Section of the NMP Work Programme (Nanostructured materials with tailored magnetic properties).

A remarbable convergence between the magnetic hard-drive industry and photonics technology is about to take place through the use of lasers to switch magnetisation at the nanoscale using plasmonics powered by a semiconductor laser. This heat assisted magnetic recording will enable storage densities of 1 terabit per square inch. The laser needs to be integrated with the read-write head and needs to operate under severe temperature conditions. The implementation of lasers in manufactured products requires the attainment of new knowledge by the magnetics industry along with the response of the academic industry to the new performance challenges. These goals can only be reached through a strong collaborative programme between industry and academia. The scientific programme is to study the properties of III-V materials to allow higher temperature operation and to study the reliability of lasers when formed by etching. The knowledge will be transferred through the cross-border secondment of staff and researchers between Seagate and the Tyndall National Institute.

The aim of this proposal is to create a training network in the newly-emerging multidisciplinary field of nano-opto-magnetism, a new scientific area with novel technological opportunities at the junction of coherent nonlinear optics, nanoscience and magnetism. The impact on society of this newly emerging field is potentially very high, therefore it is decisive that now young researchers are trained and equipped, so that they can become future leaders. We aim at achieving this by an integrated combination of a high-quality training program and their direct involvement in front-line research. In the research program we want to investigate nonthermal effects of light on nanomagnets in order to obtain a comprehensive understanding of physical mechanisms leading to a highly efficient ultrafast (10-12 seconds and faster) optical control of magnetism at the nanoscale. Such scientific breakthroughs are expected to develop novel technology for unprecedented fast (THz) opto-magnetic recording. A high-level training program firmly embedded in a consortium of both academic and industrial partners is designed to create a unique training environment to educate a new generation of young researchers in this interdisciplinary, recently emerging area of nano-opto-magnetism. In order to advance the young researchers career development, the industrial relevance of this research as well as the involvement of industrial partners is fully exploited. In addition to the scientific and networking training, this offers unique opportunities for training of complementary skills of the fellows such as training in intellectual property rights, patent writing, commercial exploitation of the results and research-and-development policy.

The creation of large magnetic fields is a necessary component in many technologies, ranging from magnetic resonance imaging, electric motors and generators, and magnetic hard disk drives in information storage. This is typically done by inserting a ferromagnetic pole piece with a large magnetisation density MS in a solenoid. In addition to large MS, it is usually required or desired that the ferromagnet is magnetically soft and has a Curie temperature well above the operating temperature of the device. A variety of ferromagnetic materials are currently in use, ranging from FeCo alloys in, for example, hard disk drives, to rare earth metals operating at cryogenic temperatures in superconducting solenoids. These latter can exceed the limit on MS for transition metal alloys given by the Slater-Pauling curve. This article reviews different materials and concepts in use or proposed for technological applications that require a large MS, with an emphasis on nanoscale material systems, such as thin and ultra-thin films. Attention is also paid to other requirements or properties, such as the Curie temperature and magnetic softness. In a final summary, we evaluate the actual applicability of the discussed materials for use as pole tips in electromagnets, in particular, in nanoscale magnetic hard disk drive read-write heads; the technological advancement of the latter has been a very strong driving force in the development of the field of nanomagnetism. © 2016 AIP Publishing LLC.

In an effort to achieve large high-field magnetization and increased Curie temperature, polycrystalline DyRh, (DyRh)95X5 and (DyRh)85X15 (X = Fe, Co, Ni, Gd) thin films have been prepared via ultra-high vacuum dc co-sputtering on SiO2 and Si wafers, using Ta as seed and cap material. A body-centred cubic CsCl-like crystal formation (B2 phase) was achieved for DyRh around the equiatomic equilibrium, known from single crystals. The maximum in-plane spontaneous magnetization at T = 4 K in fields of μ0H = 5 T was found to be μ0MS,4K = (1.50 ± 0.09) T, with a ferromagnetic transition at TC = (5 ± 1)K and a coercivity of μ0HC,4K [D] = (0.010 ± 0.001)T (at T = 4 K) for layers deposited on substrates heated to 350 °C. Samples prepared at room temperature exhibited poorer texture, smaller grains and less B2-phase content; this did impact on the Curie temperature, which was higher compared to those layers with best crystallisation. However, the maximal magnetization remained unaffected. Ferromagnetic coupling was observed in ternary alloys of DyRhGd and DyRhNi with an increased Curie temperature, larger initial permeability and high-field magnetization, which was best for (DyRh)85Gd15 with μ0MS,4K [Gd15] = (2.10 ± 0.13) T. DyRhFe and DyRhCo showed antiparallel coupling of spontaneous magnetic moments. © 2014 IOP Publishing Ltd.

Despite being the most suitable candidates for solenoid pole pieces in state-of-the-art superconductor-based electromagnets, the intrinsic magnetic properties of heavy rare earth metals and their alloys have gained comparatively little attention. With the potential of integration in micro and nanoscale devices, thin films of Gd, Dy, Tb, DyGd and DyTb were plasma-sputtered and investigated for their in-plane magnetic properties, with an emphasis on magnetization versus temperature profiles. Based on crystal structure analysis of the polycrystalline rare earth films, which consist of a low magnetic moment fcc layer at the seed interface topped with a higher moment hcp layer, an experimental protocol is introduced which allows the direct magnetic analysis of the individual layers. In line with the general trend of heavy lanthanides, the saturation magnetization was found to drop with increasing unit cell size. In situ annealed rare earth films exceeded the saturation magnetization of a high-moment Fe65Co35 reference film in the cryogenic temperature regime, proving their potential for pole piece applications; however as-deposited rare earth films were found completely unsuitable. In agreement with theoretical predictions, sufficiently strained crystal phases of Tb and Dy did not exhibit an incommensurate magnetic order, unlike their single-crystal counterparts which have a helical phase. DyGd and DyTb alloys followed the trends of the elemental rare earth metals in terms of crystal structure and magnetic properties. Inter-rare-earth alloys hence present a desirable blend of saturation magnetization and operating temperature. © 2014 IOP Publishing Ltd.

The ever-expanding demand of the world market leads to magnetic recording data storage devices advancing toward much smaller dimensions and higher storage capacities. In order to achieve capacities beyond 2TB/in2 next generation magnetic recording head transducers will require improved high moment magnetic material together with novel write pole and shield structures to preserve the necessary magnetic flux on reduced device dimensions. The implementation of novel high moment magnetic materials and design in manufactured products requires the attainment of new knowledge by the magnetics industry along with the response of the academic industry to the new performance challenges. These goals can only be reached through a strong collaborative programme between industry and academia. The scientific programme is to study the properties of magnetic materials to enable higher moment than the presently attainable limits. Nanoscale engineering of magnetic thin films will be the main approach to achieve this. The knowledge will be transferred through the cross-border secondment of staff and researchers between Seagate, Duisburg-Essen and Uppsala, utilizing the complementary expertise of the three nodes regarding state-of-the-art experimental and computational techniques as well as device fabrication.

Demand for data storage continues to grow at a rate of over 40% in part a result of the movement to cloud storage. Most of the world’s digital information is and will continue to be stored on hard drives. Innovation in the read-write transducer, from which information is recorded and read, is critical to increased hard drive data capacity. Today, 25% of the worlds transducers are manufactured in the UK giving us a unique opportunity to grow as demand for this complex nano-engineered component increases. This project will deliver a smart hard drive with improved data capacity using atomically engineered materials to enable Heat Assisted Magnetic Recording (HAMR). Smart materials, engineered at the atomic scale, will boost performance and reliablity for HAMR hard drives, decreasing time to market. Seagate is a leader in developing HAMR technology and we will demonstrate the feasibility read-write transducers with these new engineered materials.

Glass has been a key material for many important advances in civilization; it was glass lenses which allowed microscopes to see bacteria for the first time and telescopes which revealed the planets and the moons of Jupiter. Glassware itself has contributed to the development of chemical, biological and cultural progress for thousands of years. The transformation of society with glass continues in modern times; as strands of glass optical fibres transform the internet and how we communicate. Today, glasses have moved beyond transparent materials, and through ongoing research have become active advanced and functional materials. Unlike conventional glasses made from silica or sand, research is now producing glasses from materials such as sulphur, which yields an unusual, yellow orange glass with incredibly varied properties. This next generation of speciality glasses are noted for their functionality and their ability to respond to optical, electrical and thermal stimuli. These glasses have the ability to switch, bend, self-organize and darken when exposed to light, they can even conduct electricity. They transmit light in the infra-red, which ordinary glass blocks and the properties of these glasses can even change, when strong light is incident upon them. The demand for speciality glass is growing and these advanced materials are of national importance for the UK. Our businesses that produce and process materials have a turnover of around £170 billion per annum; represent 15% of the countrys GDP and have exports valued at £50 billion. With our proposed research programme we will produce extremely pure, highly functional glasses, unique to the world. The aims of our proposed research are as follows: - To establish the UK as a world-leading speciality glass research and manufacturing facility - To discovery new and optimize existing glass compositions, particularly in glasses made with sulphur - To develop links with UK industry and help them to expit these new glass materials - To demonstrate important new electronic, telecommunication, switching devices from these glasses - To partner other UK Universities to explore new and emerging applications of speciality glass To achieve these goals we bring together a world-class, UK team of physicists, chemists, engineers and computer scientists from Southampton, Exeter, Oxford, Cambridge and Heriot-Watt Universities. We are partners with over 15 UK companies who will use these materials in their products or contribute to new ways of manufacturing them. This proposal therefore provides a unique opportunity to underpin a substantial national programme in speciality-glass manufacture, research and development.
