Simulation of Magnetization Behavior in Impurity Doped Manganites

Abstract

We carried out three-dimensional Ising model calculation of Cr-doped manganites LaCr_xMn_1-xO₃, using the Monte Carlo method, to study their magnetization behavior. The magnetic interaction between Mn³⁺ and Cr³⁺ is generally thought to be ferromagnetic, in accordance with the Kanamori-Goodenough rules, whereas our calculation suggests that the magnetic interaction should be antiferromagnetic. These calculation results agree well with the experimental results.
