Sm22Co78/Fe65Co35/Sm22Co78/Fe65Co35 multilayer films were prepared by magnetron sputtering. The temperature dependence of coercivity (H-c), remanence (M-r) and reduced remanence (M-r/M-s) has been measured. The coercivity decreases with increasing of temperature. The remanence decreases with increasing the temperature from 26 to 100 degrees C, and then increases with continuously increasing the temperature from 100 to 150 degrees C. The reduced remanence increases with increasing the temperature.
