The antiferromagnetic photovoltaic effect

It is established that the photovoltaic effect may occur in centroantisymmetric antiferromagnets. It is due to nontrivial transformations of the antiferromagnetic vector upon atomic transposition under the action of crystallochemical symmetry group elements of a medium. The direction of the photovoltaic current is shown to be governed by the crystal symmetry, its exchange magnetic structure, and the orientation of the antiferromagnetic vector about the crystallographic axes.
