摘要
A study of exchange-biased Ni films with perpendicular magnetic anisotropy is presented. Polar magneto-optic Kerr effect measurements on unbiased Si(0 0 1)/Cu/Ni/Cu films reveal high out-of-plane remanence and a loop squareness close to unity. After deposition of an antiferromagnetic layer on top of the Ni film the magnetization direction remains perpendicular to the film plane and for FeMn, IrMn, and NiMn a shift in the hysteresis loop is observed. The perpendicular exchange bias is largest for FeMn, considerably smaller for IrMn and NiMn, and zero for PtMn. All anti ferromagnetic films exhibit a (0 0 1) oriented texture. © 2004 Elsevier B.V.
