Low field magnetocaloric effect in the double perovskite Sr2CrMoO6: Monte Carlo simulation
چکیده انگلیسی
Magnetocaloric effect (MCE) in double perovskite (DP) Sr2CrMoO6 has been investigated for low magnetic field change by using a Monte Carlo Simulation (MCS) in the framework of Ising model. Total magnetization and thermal derivative of the magnetization have been investigated. Magnetic entropy change has shown a significant extension around the transition temperature which is primordial for magnetic refrigeration. At transition temperature (TC) equal to 458K, the maximum of magnetic entropy change, the adiabatic temperature change and the Relative Cooling Power (RCP) have shown an increase from 1.427 to 2.582J·Kg−1K−1, from 5.43 to 8.71K, and from 18.33 to 28.62J·kg−1, respectively, for magnetic field changes 100Oe and 700Oe, which is large for low magnetic field compared to other magnetocaloric materials. The Large MCE at low-field makes Sr2CrMoO6 a very promising candidate for magnetic refrigeration above room temperature.
