The Reorientation Temperature in an Antiferromagnetic Monolayer

Abstract

The reorientation temperature in an antiferromagnetic square lattice is studied within the framework of many-body Green function theory. The model Hamiltonian includes a Heisenberg term, second-order single-ion anisotropy, and a transverse external magnetic field in the x-direction. We investigate the orientation temperature as a function of the single-ion anisotropy parameter and for different transverse magnetic fields.

“…1B) Figure 1A and B shows that the reorientation temperatures are different in the both sublattices. On other hand, the reorientation temperatures in antiferromagnetic systems in both sub-lattices are the same [4]. From Fig.…”
