摘 要：<正>SmxCo5（x = 1.3, 0.7, 0.4） thin films were prepared by magnetron co-sputtering technique. The samples were annealed at 723 K under Ar atmosphere. The annealed time was chosen as 30 min. The hysteresis loops of the samples were measured under the ac applied magnetic field with the period Tp（2πω） , H（t） = H0sin（ωt）, by vibrating sample magnetometer （VSM）. The experimental results indicate that, （1） the average hysteresis loop areas as functions of the values of H0 andωdisplay a power scaling law with the exponents, A = A0 + H0αωβ; （2） the x composition of SmxCo5 film has evident effect on the scaling behavior and magnetic properties; （3） the anisotropy scaling exponents exist clearly in the anisotropy SmxCo5 thin films. Moreover, the scaling behavior of the anisotropy magnetic film was also simulated with Monte Carlo method. The simulated results are consistent with the experimental fact.
