NiFe-seeded magnetic tunnel junctions (MTJs) of IrMn/CoFe/MgO/CoFeB were successfully formed by radically oxidizing a thin Mg layer. Room temperature (RT) tunnel magnetoresistance (TMR) of up to 211 ± 10% was obtained and found to be strongly dependent on the thickness of the NiFe seed layer. High resolution transmission microscopy (HRTEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and magneto-optic Kerr effect (MOKE) analyses performed on NiFe/IrMn bilayer systems revealed that the IrMn(111)-fcc texture, grain size, surface roughness (rms), and exchange-biasing field (H ex) were strongly affected by the thickness of the NiFe seed layer. A critical NiFe thickness (tc ≈ 12 Å) was found: For t NiFe ≤ t c, the IrMn showed a very poor (111)-fcc texture with reduced grain size, very smooth surface, and reduced H ex. For t NiFe > t c, the IrMn showed a complete opposite behavior: much enhanced (111)-fcc texture with larger grain size, rougher surface, and larger H ex. For MTJ-based IrMn systems, a striking behavior is reported: larger TMRs and lower tunnel junction resistance (RA) products are obtained for t NiFe ≤ t c while lower TMRs and larger RAs are obtained for t NiFe > t c. © 2012 The Japan Society of Applied Physics.

In 2009, Japanese government has proposed the economic recovery policy which adverts to the "urban mine." One of it's purpose is to recycling of waste plastic from urban areas. It is very reasonable but is unperformed efficiently. In this review, I will discuss the possibility of the plastic liquefaction technology to the urban oil field. It has come to be feasible to make oil from waste plastics in these days. It will be more effective if the tax system for the sale of the cracked oil is studied. Heavy oil (waxy oil) and light oil (naphtha) made from the waste plastics can be valuable resource for near future on the progress of the study of social system. The feedstock recycle (the product is light oil) must be promoted. Japan is superior to other countries in such technology, so we must assist the recycle technology of the foreign countries as Asian countries. Source
