  1. The saturation magnetization is roughly unchanged. The effective magnetization Meff obtained through broad-Band FMR measurements allow to deduce the out-of-plane anisotropy fields HKU (HKU = Ms − Meff) confirming the dramatic changes of the out-of-plane magnetic anisotropy variations observed in the hysteresis curves
