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 (Fep^IIMn1-p^II)1.5[Cr^III(CN)6].nH2O consisting of three different Ising spins SA=3/2, SB=2, and Sc=5/2. We have found that the critical temperature Tc of this system nearly linear changes dependent upon the interaction ratio R for any mixing ratio p value, and the critical interaction Rc 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 Tcomp 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 (Fep^IIMn1-p^II)1.5[Cr^III(CN)6].nH2O.
