Abstract

Abstract In this work we use Monte Carlo (MC) simulations to study the magnetic properties of a double perovskite nano Sr 2 VMoO 6 , with crystal and magnetic fields. The crystal structure of Sr 2 FeMoO 6 is constituted of two magnetic cubic sub-lattices: The sub-lattice (I) is occupied by the V 3+ magnetic ions with a magnetic moment S = 1, while the sub-lattice (II) is occupied by the Mo 5+ magnetic ions with a magnetic moment σ = 1/2. A number of interesting phenomena such as the blocking temperature, the exchange interaction coupling between V 3+ and Mo 5+ ions, the size and temperature effects, at fixed values of the crystal field, have been investigated. On the other hand, the response of the magnetization to the field is illustrated in the hysteresis loops.
