Abstract (in Japanese) (See Japanese page) 
(in English) We report the crystal structures and magnetic properties of r-plane oriented [Pt/Co]3/Pt/Cr2O3 multilayers fabricated by DC-RF magnetron sputtering method. The grown grains showed elongated shapes along [-111]. The orientation and lattice parameter of Cr2O3 film was checked from x-ray diffraction experiment. (n -n 0 2n) type diffraction signals were observed in 2θ-θ pattern where n=integer, indicating the r-plane oriented deposition. The lattice parameter was 0.363 nm, which was in agreement with that of the bulk. The magnetic property of the multilayer was investigated from magnetic field (H) and temperature (T) dependences of the in-plane and out-of-plane magnetizations (M). The double hysteresis character was observed in in-plane M-H curve at 5 K~180 K. Hysteresis loop disappeared at 200K or more, it showed the behavior of superparamagnetic. For out-of-plane, closer results were obtained. Saturation magnetic in-plane larger than. Axis of Easy Magnetization is found that is suitable for in-plane.
