Co-ITO granular magnetoresistance films fabricated by precipitation of magnetic nanoparticles from amorphous oxide J.A nanometer-scale hybrid film of Co particle/Co-C 60 compound was prepared by alternate deposition of Co and C 60 under UHV condition. All of Raman spectra, magnetization curves, and tunnel conductivity concluded that the hybrid system has a granular structure consisting of Co nanoparticles embedded in a Co-C 60 compound matrix. The magnetoresistance ratio of 26% was obtained at 2 K and 10 kOe for the electron tunneling across the Co-C 60 compound barrier. In addition, anomalously large bias voltage dependence was found in the magnetotransport properties.

Aim:The aim of this study was to clinically evaluate percutaneous endoscopic gastrostomy (PEG) tube feeding of elderly Japanese patients with dementia.Method: The records of the 155 patients with dementia who underwent PEG in Juntendo Tokyo Koto Geriatric Medical Center were reviewed for pertinent clinical data, including diagnosis of dementia, place of stay before and after hospitalization, as well as survival rate, albumin levels, and incidence of aspiration pneumonia (AP) before and 6 months after PEG feeding. The latter three data of these patients were compared with those of 106 patients with dementia fed through a nasogastric (NG) tube.

The axial orientation of molecular-beam-epitaxy (MBE)-grown Fe3Si(111)∕Ge(111) hybrid structures was investigated by Rutherford backscattering spectroscopy. We confirmed that during MBE above 300°C, the interdiffusion of Fe and Ge atoms results in a composition change and the epitaxial growth of FeGe in Fe3Si. Low-temperature (<200°C) MBE can realize fully ordered DO3–Fe3Si with highly axial orientation [minimum yield (χmin)=2.2%]. Postannealing above 400°C results in a composition change and the degradation of axial orientation in the off-stoichiometric Fe3Si. The significance of stoichiometry with regard to thermal stability and the interfacial quality of Fe3Si(111)∕Ge(111) hybrid structures was also discussed.
