Abstract

An atomic model of the direct exchange coupling in an antiferromagnetic (AF) and ferromagnetic (FM) bilayer has been investigated. Exchange anisotropy is achieved by different mechanisms in the body-centred-cubic and face-centred-cubic FM layers. For the former, the formation of an AF domain wall directly causes the exchange anisotropy. For the latter, a cooperative effect in the AF domain wall and the asymmetric form of the uncompensated AF spins produces the exchange anisotropy.
