The three dimensional anisotropic XY ferromagnet has been studied by Monte Carlo simulation. The ferro-para phase transition has been observed to take place at a lower temperature for impure anisotropic XY ferromagnet. The pseudocritical temperature ($T_c^*$) has been found to decrease as the system gets more and more impure (impurity concentration $p$ increases). In the case of bilinear exchange type of anisotropy ($lambda$), the pseudocritical temperature ($T_c^*$) increases linearly with $lambda$ for any given concentration of nonmagnetic impurity ($p$). The slope of this linear function has been found to depend on the impurity concentration ($p$). The slope decreases linearly with the impurity concentration ($p$). In the case of the single site anisotropy ($D$), the pseudocritical temperature ($T_c^*$) has been found to decrease linearly with $p$ for fixed $D$. The critical temperature (for a fixed set of parameter values) has been estimated from the temperature variation of fourth order Binder cumulants ($U_L$) for different system sizes ($L$). The critical magnetisation ($M(T_c)$) and the maximum value of the susceptibility ($chi_p$) are calculated for different system sizes ($L$). The critical exponents for the assumed scaling laws, $M(T_c) sim L^{-{{beta} over {nu}}}$ and $chi_p sim L^{{{gamma} over {nu}}}$, are estimated through the finite size analysis. We have estimated, ${{beta} over {nu}}$, equals to $0.48pm0.05$ and $0.37pm0.04$ for bilinear exchange and single site anisotropy respectively. We have also estimated, ${{gamma} over {nu}}$ equals to $1.78pm0.05$ and $1.81pm0.05$ for bilinear exchange and single site anisotropy respectively.
通过蒙特卡罗模拟研究了三维各向异性 XY 铁磁体。对于不纯的各向异性 XY 铁磁体，铁-para 相变发生在较低的温度下。假临界温度（$T_c^*$）随着系统越来越不纯（杂质浓度 $p$ 增加）而降低。在双线性交换型各向异性（$lambda$）的情况下，对于任何给定浓度的非磁性杂质（$p$），伪临界温度（$T_c^*$）与$lambda$呈线性增长。该线性函数的斜率取决于杂质浓度（$p$）。斜率随杂质浓度（$p$）的增加而线性减小。在单点各向异性（$D$）的情况下，在固定的$D$条件下，伪临界温度（$T_c^*$）随$p$线性下降。临界温度（针对一组固定参数值）是根据不同系统大小（$L$）的四阶宾德累积量（$U_L$）的温度变化估算出来的。临界磁化率（$M(T_c)$）和磁感应强度最大值（$chi_p$）是根据不同的系统尺寸（$L$）计算得出的。通过有限尺寸分析，我们估算出了假定缩放定律的临界指数：$M(T_c) sim L^{-{{beta} over {nu}}$ 和 $chi_p sim L^{{{gamma} over {nu}}$ 。我们估计，对于双线性交换和单点各向异性，${{mega} over {nu}}$ 分别等于 0.48 和 0.04 美元。我们还估计，${{gamma} over {nu}}$ 分别等于 1.78 （pm0.05）$ 和 1.81 （pm0.05）$，用于双线性交换和单点各向异性。
