Monte Carlo Study of the Magnetic Behaviors in a Ferrimagnetic Ising Quadruple Perovskite

In this work, the magnetic properties and the magnetic hysteresis behavior of the C a C u 3 M n 2 O s 2 O 12 quadruple perovskite with ferrimagnetic mixed-spin (1/2, 2, 3/2) Ising spin configuration under the influence of different physical factors such as exchange coupling, crystal field and temperature have been studied by using Monte Carlo simulation. The ground-state phase diagrams were numerically calculated to determine the stable phases. Particular emphasis is given to the effects of the exchange interaction J Mn - Mn and the single-ion anisotropy strength D Mn , of the sublattice with larger spin, on the critical and the compensation phenomenon. The thermal partial–total magnetizations and their change have been obtained. Some interesting behaviors have been observed which include the first- and second-order phase transitions. The isolated critical points are also observed. The magnetic hysteresis loops are discussed and a triple hysteresis loops have been observed for appropriate values of the system parameters. Then, the thermal behaviors of the coercivity and the remanent magnetization are also elaborated and investigated.
