Pyromagnetic effect in ferrimagnets with a ’weak’ sublattice

Lomonosov Moscow State University, Department of Physics, Leninskie Gory 1 build. 2, Moscow, 119991, Russian Federation

The temperature dependence of the residual and spontaneous magnetization in ferrites with a ’weak’ sublattice may be taken as evidence for the pyromagnetic effect — a magnetic analog of the pyroelectric effect — in which the magnetization of a sample increases on cooling in the absence of an external magnetic field. A confirmation of this has been provided by the observation of a thermodynamically inverse phenomenon, the linear magnetocaloric effect, in such ferrites. These effects are due to the unidirectional exchange anisotropy characteristic of ferrimagnets with a weak sublattice.
