Top exchange biasing enhancement in X/IrMn/Py and X/IrMn/Co multilayers

In this paper, we show that in the F/AF/F trilayers this effect is independent on the crystallographic quality or roughness of the antiferromagnetic layer or on magnetic interactions between the two ferromagnetic layers. On the contrary, this effect is found to be reminiscent of a domain structure induced in the antiferromagnetic layer by the underlying ferromagnetic layer during the multilayer growth.
