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.

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.

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.

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).

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.
