n this work, with help of Monte Carlo simulation method we have
investigated the effects of single-ion anisotropy on magnetic
properties of the three dimensional ternary alloy model
AB$_{p}$C$_{1-p}$ which type of the Prussian blue analog
(Fe$_{p}^{II}$Mn$_{1-p}^{II}$)$_{1.5}$[Cr$^{III}$(CN)$_{6}$].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 linearly changes dependent upon the interaction ratio
$R$ for any mixing ratio $p$ value, and critical interaction $R_{c}$
decreases for increasing $D$ values. Then, 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 depending on $D$ and
compensation temperature $T_{comp}$ decrease for increasing external
magnetic field dependent upon some values of the Hamiltonian
parameters. As a result, we state that single-ion anisotropy can be
use as a control parameter like mixing rate $p$ to arrange the
critical and compensation temperature of the Prussian blue analog
(Fe$_{p}^{II}$Mn$_{1-p}^{II}$)$_{1.5}$[Cr$^{III}$(CN)$_{6}$].nH$_{2}$O.
