Abstract

The properties of a dilute Ising magnet are studied using a two-dimensional spin–pseudospin model with charged impurities and a frustration caused by the competition of the charge and magnetic orderings. Based on the classical Monte Carlo method, the ground state phase diagram has been obtained and also unusual phase states appeared at finite temperatures have been studied. The regions in which order–order phase transitions and also reentrant phase transition are observed have been found.

带挫折的2D稀释磁体的相态的特定特征

摘要

使用二维自旋-伪自旋模型研究带电杂质和由于电荷和磁有序竞争而产生的无奈现象，从而研究了稀的伊辛磁体的特性。基于经典的蒙特卡洛方法，获得了基态相图，并研究了在有限温度下出现的异常相态。已发现观察到有序-有序相变以及折返相变的区域。
