Effects of unidirectional exchange anisotropy in ferrites

Lomonosov Moscow State University, Department of Physics, Vorobevy gory, Moscow, 119992, Russian Federation

A number of anomalous effects occurring at the compensation and Curie points of ferrites are explained on the basis of the concept of unidirectional exchange anisotropy. Among these are the violation of ’evennies’ for the magnetostrictive, magnetoresistive, and magnetocaloric effects, the antiferromagnetic paraprocess, and some other phenomena. Based on the analysis of these effects, a piezomagnetic effect is predicted to occur in ’weak-sublattice’ ferrimagnets.
