Monte Carlo study of the magnetic properties of the rare earth-based perovskite LaSr2Cr3O9

A new theoretical study of the magnetic triple perovskite LaSr 2 Cr 3 O 9 is presented in this work. The all possible configurations have been studied and discussed in the absence of any temperature ( T = 0 K). For a finite temperature value, we use Monte Carlo simulations to underline the critical behavior of this system. The transition temperature is found to be around 100 K. The dependency of the total magnetizations is a function of the reduced crystal field and the reduced external magnetic field. In addition, the hysteresis loops have been carried out for different temperature values. Finally, the reduced remanent magnetizations have been presented as a function of temperature.
