چکیده انگلیسی
The thermomagnetic properties of a Ising ferrimagnetic system on a bipartite square lattice of spins SiA=2 and ÏjB=5/2 with different single-ion anisotropies are analyzed by Monte Carlo simulations. We obtained the phase diagrams at finite temperature of the total magnetization (MT), the magnetization of sublattices (MA,MB), specific heat (C) and the total susceptibility (ÏT) per spin of the model. In the planes (D1/|J1|/kBT/|J1|) and (D2/|J1|/kBT/|J1|) the critical and compensation temperatures have been deduced. We found that single-ion anisotropy interactions play an important role for the existence of compensation temperatures. Compensation points may be present, for a specific range of crystal field of sublattice spins ÏjB=5/2, even when the anisotropy field of sublattice spins SiA=2 is zero. Mean field theory predicts a wide range of parameters where the system presents even several compensation temperatures, in most of these regions we found none.
