Abstract
Sm22Co78/Fe65Co35/Sm22Co78/Fe65Co35 multilayer films were prepared by magne tron sputtering. The temperature dependence of coercivity (H-c), remanence (M-r) and reduced remanence (M-r/M-s) has been measured. The coercivity dec reases with increasing of temperature. The remanence decreases with increas ing the temperature from 26 to 100 degrees C, and then increases with conti nuously increasing the temperature from 100 to 150 degrees C. The reduced r emanence increases with increasing the temperature.
