  The exchange bias at ferromagnetic/antiferromagnetic interfaces strongly
depends upon the state of antiferromagnetic (AF) layer which, due to strong
magnetoelastic coupling, is sensitive to mechanical stresses. In the present
paper we consider magnetoelastic effects that arise at FM/AF interface due to
lattice misfit and magnetic ordering. We show how magnetostriction affects
mutual orientation of AF and FM vectors and easy-axis direction in thin AF
layer. The results obtained could be used for tailoring exchange biased
systems.
