Özet

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.

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.
