Abstract

The temperature dependence of the amorphous Sm(Tb,Dy)FeCo quaternary alloys films was investigated using the mean-field model in combination with genetic algorithm. It is shown that when the light rare earth element Sm was substituted for the heavy rare earth element Tb or Dy, the compensation temperature (T_COMP) decreases, Curie temperature (T_C) remains unchanged and the saturation magnetization (M_s) at room temperature increases. Experimental data show good agreement with the calculated results.
