Abstract: The temperature dependences of the saturation magnetization together with the subnetwork magnetizations are calculated for various RE-Co amorphous alloy films with RE=La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, and Yb based on the mean field theory. In order to fit the simulation results to experimental data so far reported, the following assumptions are required as for the magnetic structure : (1) the magnetic moment μ_<RE> of RE atom must be smaller than the theoretical value for the (RE)^<3■> ion except for RE=Gd, (2) especially in cases of RE=Ce and Sm μ_<RE> must be zero as in La, and (3) the compositional dependence of the Co magnetic moment μ_<Co> is almost the same independent of the RE species except RE=Ce. The Curie temperature as well as the compensation temperature are shown for a whole RE-Co system.
