论文摘要
在这项工作中，我们进行了蒙特卡洛模拟，以研究平方和立方晶格上的混合自旋-1和旋转-3/2 iSing铁磁系统以及两个不同的单离子各向异性。该晶格分为两个带旋转$ s^a = 1 $（$ \ pm1 $和0）的互穿旋转的转子，上面是sublattice $ a $ a $ a $ a $ a $ a $ a $和$ s^b = 3/2 $（sublattice $ b $ b $ b $。我们已经使用了单离子各向异性$ d_ {a} $和$ d_ {b} $在Sublattice $ a $ a $ a $ and $ b $上作用的。我们已经确定了模型在温度$ t $中的相图与单离子各向异性强度$ d_a $和$ d_b $平面，并表明该系统表现出二阶和一阶相变。我们还表明，该系统显示了各向异性值的补偿点。
In this work, we have performed Monte Carlo simulations to study phase transitions in a mixed spin-1 and spin-3/2 Ising ferrimagnetic system on the square and cubic lattices and with two different single-ion anisotropies. This lattice is divided in two interpenetrating sublattices with spins $S^A = 1$ (states $\pm1$ and 0) on the sublattice $A$ and $S^B = 3/2$ (states $\pm 3/2$, $\pm 1/2$) on the sublattice $B$. We have used single-ion anisotropies $D_{A}$ and $D_{B}$ acting on the sites of the sublattice $A$ and $B$, receptively. We have determined the phase diagrams of the model in the temperature $T$ versus the single-ion anisotropies strength $D_A$ and $D_B$ plane and shown that the system exhibits both second- and first-order phase transitions. We also have shown that this system displays compensation points for some values of the anisotropies.
