In this article, magnetic properties of the perovskite GdCuO₃ have been investigated by Monte Carlo simulation in the frame of the Ising model for different sizes of system. Interaction couplings have been calculated, phase diagrams of ground state have been established and the orthorhombic crystal structure has been deduced. Couplings of first, second and third order interactions were found respectively 71.016K, 51.057K and 26.805K.The system is an antiferromagnetic order at the ground state. Simulation results showed that the Curie temperature $T_C$ of GdCuO₃ system is around 750K. In addition, it has been observed that as the size of the lattice increases, critical temperature also increases. Based on the results this material could be considered a good candidate for applications requiring higher $T_C$ values.

在本文中，钙钛矿 GdCuO _{3 的}磁性能已通过蒙特卡罗模拟在 Ising 模型的框架内针对不同尺寸的系统进行了研究。计算了相互作用耦合，建立了基态相图并推导了正交晶体结构。发现一阶、二阶和三阶相互作用的耦合分别为71.016K、51.057K和26.805K。系统在基态为反铁磁有序。仿真结果表明，居里温度${吨}_C$GdCuO ₃系统的温度约为750K。此外，已经观察到随着晶格尺寸的增加，临界温度也增加。根据结果​​，这种材料可以被认为是要求更高的应用的理想选择${吨}_C$ 值。
