Abstract

In this paper, an approximation method has been used to calculate Super Exchange (SE) and the Double Exchange (DE) couplings in the Double Perovskite (DP) structure of Sr2CrWO6. The method relies on a relation between internal energy per site and magnetization per site and Monte Carlo simulation in the framework of Ising model. A new model parameter has been proposed and varied to find the exchange couplings that verify the experimental Curie temperature measured under an external field h=0.01T. SE coupling has been found equal to −7.554 meV and the DE couplings corresponding respectively to Cr and W ions have been found equal to 17.629 and 5.661 meV. Internal energy per site has been calculated.
