Abstract
A lateral shift, similar to a Goos-Hanchen shift, of a normally incident
electromagnetic beam reflected of an antiferromagnet in the presence of
an external magnetic field is predicted. This shift is interpreted in
terms of nonreciprocity of the reflected phase, and is confirmed using
numerical simulation. There is also a lateral displacement of the field
within the antiferromagnet, but not of the beam transmitted through an
antiferromagnetic slab. Copyright (c) EPLA, 2008.
