In order to enhance the crystalline field and to study the molecular field change by Al substitution for Fe, the Al content dependence of the spin reorientation temperature TSR was studied both experimentally and theoretically for R2Fe17−xAlxC2 (R

Magnetic phase transition in weak random anisotropy magnets amorphous a-HoFe and ErFe thin films with “in-plane” coherent anisotropy are studied by measurements of temperature (T) dependence of ac susceptibility. We observed distinct difference i

The temperature dependences of Faraday rotation spectra (FRS) at around 1.5 μm are measured at temperatures between 60 and 300 K for a single crystalline Co 2+ -substituted magnetic garnet film grown by a liquid-phase epitaxy method onto a gadoliniu

The temperature dependence of the Faraday rotation (FR) spectra is measured at temperatures between 60 and 300 K in the wavelength range of 0.7–1.6 μm for single crystalline (Y3+, Ca2+)3(Fe3+, Rh4+)5O12 films grown by a liquid phase epitaxy method

The pressure dependence of the spin reorientation in Er 2 Fe 17 C 2 was measured by means of ac initial susceptibility under 1–12 kbar. As a result, the spin reorientation temperature shifted toward the higher side with increasing pressure. From th

Temperature dependence of magnetization in various magnetic fields H is measured for a-Pr 16 Fe 84 with a small effective ratio of random anisotropy constant D to exchange constant J and with ferromagnetic coupling between their two subnetworks. In t

The spin arrangement in Nd2Fe14B changes from conical to ferromagnetic with increasing temperature at TSR. If a field is applied perpendicular to the c-axis of the crystal,TSR increases from 143 K for zero field to 152 K for 7 kOe. In Er2Fe14B the sp

We measured the temperature dependence of the magnetization in various magnetic fields for amorphous Dy0.16Fe0.84 with a small (effective) ratio of the random anisotropy (D) to the exchange strength (J). A large bend of the irreversible line was obse

The effect of silica substrate on the exchange-coupled field H ex in NiO/Ni films was examined. Ni film was vacuum-evaporated on a silica substrate, and then it was oxidized thermally in oxygen to form a NiO/Ni double-layered film. In comparison with

The temperature dependence of the Faraday rotation in the near-infrared wavelength region is calculated in comparison with that observed in Co2+-containing hexaferrites by using the molecular field approximation. The calculation results show that the
