摘要: Abstract The magnetic behaviors of a mixed spin-2 and spin-5/2 Ising ferrimagnetic system on square lattice are studied with the mean-field approximation (MFA) based Bogoliubov inequality for free energy. A Landau expansion energy in order parameter is also described this work. In particular, we investigate effect single-ion anisotropy compensation phenomenon.
