Abstract

A symmetry analysis is presented of the possible types of magnetic ordering in hexagonal ferrimagnets having an (M type) magnetoplumbite structure. In the analysis the transition channel to a magnetically ordered state according to the k=0 star is considered. It is shown that the only general commuting representation for all regular point systems in such compounds is the unitary representation τ1 corresponding to ferromagnetic ordering of the magnetic moments in sublattices. Antiferromagnetic exchange between ions of different sublattices leads to a collinear ferrimagnetic structure.
