Abstract
In this work, with help of Monte Carlo simulation method, we have investigated the effects of single- ion anisotropy on magnetic properties of the Prussian blue analog ((FepMn1-pII)-Mn-II)(1.5)[Cr-III(CN)(6)]center dot nH(2)O consisting of three different Ising spins, S-A = 3/2, S-B = 2, and S-C = 5/2. We have found that the critical temperature T-c of this system nearly linear changes dependent upon the interaction ratio R for any mixing ratio p value, and the critical interaction R-c decreases for increasing D values. On the other hand, we have shown that the critical and compensation temperature of the model smoothly increase for increasing D values. In addition, we have demonstrated that the magnetic pole inversion can appear, and compensation temperature T-comp decreases for the increasing external magnetic field, dependent upon some values of the Hamiltonian parameters. As a result, we state that single- ion anisotropy can be used as a control parameter like mixing rate p to arrange the critical and compensation temperature of the Prussian blue analog ((FepMn1-pII)-Mn-II)(1.5)[Cr-III(CN)(6)]center dot nH(2)O.
