Magnetic properties of double perovskite : Mean field approximation and Monte Carlo simulation

The double perovskite (DP) Sr2CrReO6, with its high Curie temperature, is a good candidate for magneto-electric and magneto-optic applications. Thus, a theoretical study by Monte Carlo Simulation (MCS) and Mean Field Approximation (MFA) in the context of the Ising model is important for a better understanding of the magnetic behavior of this material. The critical behavior of the magnetization and the susceptibility of this system have been determined. The phase diagrams depending on the exchange couplings and the crystal fields have been given. The values of critical exponents are also reported.
