A microscopic model for exchange bias

Published 2001-06-18Version 1

The domain state model for exchange bias has been further investigated by considering vector spins for the antiferromagnet instead of Ising spins used in the earlier studies. The qualitative results are similar to those with infinite anisotropy for the antiferromagnet. However, under certain conditions softer spins can lead to an even stronger bias field. The study shows a nontrivial dependence of the exchange bias on the antiferromagnetic anisotropy.
