Magnetic Properties of (La0.56Ce0.14)Sr0.30MnO3 Perovskite

摘要

We investigate in this paper magnetic properties of the perovskite compound(La0.56Ce0.14)Sr0.30MnO3. The method we use here is Monte Carlo simulation, inwhich we take into account different kinds of interactions between nearest andbetween next-nearest magnetic ions Mn 3+ (S = 2) , Mn 4+ (S = 3/2) and Ce 3+ (S= 1/2). Using a classical spin model, we have calculated the internal energy,the magnetization per ion type and their corresponding magnetic susceptibility,as well as the Edwards-Anderson order parameter for each ion kind. We alsostudied the applied-field effect on the system magnetization. Our results showa good agreement with experiments.
