Abstract

The determination of exchange bias and magnetic anisotropies in a Co layer in a single-crystalline FeF₂ film was reported. A model was developed that quantitatively described the exchange bias and the anisotropies over the whole temperature range, both above and below Néel temperature T_N. It was shown that large magnetic anisotropies were induced in a ferromagnetic film deposited on an antiferromagnetic substrate even well above T_N of the antiferromagnet.
