Magnetic Behavior of Ternary Prussian Blue Analog in Presence Single-Ion Anisotropy

OpenAlex İngilizce

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${({\rm Fe}_{p}^{\rm II}{\rm Mn}_{1-p}^{\rm II})}_{1.5}[{\rm Cr}^{\rm III}({\rm CN})_{6}].{\rm nH}_{2}{\rm O}$consisting of three different Ising spins${\rm S}_{A}=3/2$,${\rm S}_{B}=2$, and${\rm S}_{c}=5/2$. 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$T_{\rm comp}$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${({\rm Fe}_{p}^{\rm II}{\rm Mn}_{1-p}^{\rm II})}_{1.5}[{\rm Cr}^{\rm III}({\rm CN})_{6}].{\rm nH}_{2}{\rm O}$.
