Using mean-field theory and experimental Ms Value of (Smo. 343 Tb0.657 )31 C069/ Cr with different temperature, the temperature dependence curve of (Sm0. 156Tb0.844)31 Co69 thin film is simulated and calculated, the calculation results are in good accord with experimental results. Both the theory and experimental results show that the Curie point of thin film is around 200℃, and at room temperature, the magnetic anisotropy e...
