Specific Features of Phase States of a Diluted 2D Magnet with Frustration

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.
