Abstract

The magnetic properties of ferromagnetic La0.7Ca0.33MnO3 perovskite have been studied using Monte Carlo simulations within the Ising model framework. The considered Hamiltonian includes the first nearest neighbor, an external magnetic field, and a crystal field. The thermal magnetizations and magnetic susceptibilities are computed for a fixed system size N = 5. In addition, the critical temperature is deduced. The magnetization versus the exchange interactions and crystal field are deduced for a fixed system size. The magnetic hysteresis cycle versus temperature is also established.
