摘要:

The magnetic properties of inverse ferrite (Fe3+) [Fe3+Co2+]O42-,(Fe3+) [Fe3+Cu2+]O42-,(Fe3+) [Fe3+Fe2+]O42-, and (Fe3+) [Fe3+Ni2+]O42- spinels have been studied using Monte Carlo simulation. We have also calculated the critical and Curie Weiss temperatures from the thermal magnetizations and inverse of magnetic susceptibilities for each system. Magnetic hysteresis cycles have been found for the four systems. Finally, we found the critical exponents associated with magnetization, magnetic susceptibility, and external magnetic field. Our results of critical and Curie Weiss temperatures are similar to those obtained by experiment results. The critical exponents are similar to those of known 3D-Ising model.
