Abstract
Environmental friendly double perovskite Sr2TiMoO6 has been studied by using the density functional theory with generalized gradient approximation (GGA+U) approaches, and the Monte Carlo simulation in the framework of Ising model. The parameter of the unit cell has been optimized. The value of the crystal field and the exchange coupling have been estimated from the partial electronic density of states and the energy calculations, respectively. The magnetic properties and the magnetocaloric effect of the compound have been also studied. The Relative cooling power has been performed. It is found that Sr2TiMoO6 is an interesting material for the magnetic refrigeration applications.
