Opis:: The magnetic anisotropy of reentrant spin glass NiMn thin film, in the vicinity of the ferromagnetic Ni film, is investigated using NiMn/Ni, Cu/Ni/Cu (t=10 Å and 500 Å)/NiMn and NiMn/Ni/Cu (t=10 ÷ 5000 Å)/Ni films. The unidirectional anisotropy field of NiMn layer in NiMn/Ni film is smaller than that of bulk NiMn. In Cu/Ni/Cu (t=10 Å and 500 Å)/NiMn film, the unidirectional anisotropy field is almost independent of the Cu spacer thickness. These results can be explained in terms of magnetic coupling between the magnetic layers in addition to the film structure of NiMn layer.

Opis:: Image depth profiling AES incorporating an image processing technique has been developed. This method reconstructs a cross-sectional image from acquired 2-dimensional and/or 3-dimensional data. A binary image produced from a secondary electron image through image processing can be used to cut the area of interest for selected area analysis. In a failure analysis of a relay contact, we found by cross-sectional image observation that Fe and Ni permeate from pin holes in an Au layer covering a Fe-Ni alloy. A VTR head made of a polycrystalline ferrite core covered with a Sendust (Si-Al-Fe alloy) layer at the gap has been analyzed. Depth distributions of Al, 0, and Fe on different grains, and Al and O distributions near grain boundaries have been successfully reassembled from the 3-dimensional data.

Opis:: The photo-induced decrease in magnetization ΔM$\text{}_{photo}$ was observed in Cd$\text{}_{1-x}$Mn$\text{}_{x}$Te (0.25 < x < 0.42) under unpolarized light illumination whose photon energy is smaller than the band gap of the sample. The photo-induced magnetization decreases with increasing Mn content through Mn$\text{}^{2+}$-Mn$\text{}^{2+}$ antiferromagnetic interaction, which supports our idea for origin of it based on the flipping of Mn spins in the bound magnetic polarons accompanied by the spin-flip Raman scattering.
