The structure and magnetic properties of Sm-Co films and Sm-Co/M (M=Co, Fe) multilayered films prepared by rf sputtering were investigated. The results show that a hard magnetic phase as Sm<SUB>2</SUB>Co<SUB>17</SUB> and SmCo<SUB>5</SUB> phase and a soft magnetic phase were formed by annealing Sm-Co and Sm-Co/M films. Sm<SUB>16</SUB>Co<SUB>84</SUB> film annealed for 1.8 ks at 773 K had the springback ratio of [Mr-M(H)]/[Mr-M(H)]=0.72. This film was found to behave as a exchange-spring magnet composed of a hard magnetic phase and a soft magnetic phase. Sm<SUB>16</SUB>Co<SUB>84</SUB>/Fe multilayered film was also found to be a exchange-spring magnet.
