Abstract :
Measurements of the time dependence of magnetization at various reversing fields and remanence coercivity in Tbx(Fe90Co10)100-x films (x = 13 ∼ 31) where the compensation composition is x = 22.5, indicate that the thermal stability in transition metal-rich films is better than that in the rare earth-rich ones. There seems to be a difference in (KuV/kBT) between the TM-rich and RE-rich compositions.
