Magnetic reorientation in a ferrimagnetic monolayer



The Green function theory is used to study theoretically the magnetic reorientation phase transition (MRPT) in a two-sublattice ferrimagnetic monolayer, with spin SA and SB at the sublattice A and B sites, respectively. The result is that MRPT in the sublattices A and B occurs at different reorientation temperatures. We can assume that presented model confirms the possibility of two magnetic phases in ferrimagnetic systems.
