摘要
The magnetic stability of two different interfacial exchange coupled systems is investigated using the magneto-optic Kerr effect during repeated reversal of the soft layer magnetization by field cycling up to 10(7) times, For uniaxial Fe/Cr(211) exchange biased "double-superlattice" systems, small but rapid initial decay of exchange bias field HE and the remanent magnetization is observed. Also the Sm-Co/Fe bilayers grown epitaxially with uniaxial in-plane anisotropy show similar decay, However, the HE Of biaxial and random in-plane bilayers shows gradual decay without large reduction of the magnetization. These different decay behaviors are explained by their different microstructure and interfacial spin configurations. (C) 2000 American Vacuum Society. [S0734-2101(00)02104-7].
