The dependence of reduced remanence (Mr/Ms) and coercivity of Sm22Co78/Fe65Co35 bilayer and Sm22Co78/Fe65Co35/Sm22Co78 triple-layer films on Fe65Co35 soft-magnetic layer thickness d, was systematically investigated. All the hysteresis loops of the films exhibited a single-phase behavior, reflecting a strong exchange coupling between soft-and hard-magnetic phase. Mr/Ms showed a monotonic increase with increasing Fe65Co35 thickness d, and the coercivity would show a peak with increasing d. From the plot of M versus applied field H, it is shown that the positive profile decreases and the negative interaction profile increases with the increase of interfaces between soft-and hard-layers.
