Exchange bias in FeF2–Co/Pt heterosystems with perpendicular anisotropy

Abstract The exchange bias effect is measured in heterosystems with perpendicular anisotropy consisting of Co/Pt multilayers on top of the (0 0 1) face of a FeF 2 single crystal. The resulting exchange field H E exhibits a strong dependence on temperature and the axial freezing field, H F . Within the framework of an Ising-type model, the H E vs. T as well as the H E vs. H F data are explained in terms of the microscopic spin structure at the interface.
