Dynamic Hysteresis Properties of Mixed Spin (1, 5/2) Ising Ferrimagnetic Blume-Capel Model: An Effective-Field Theory Analysis

摘要

The dynamic hysteresis behaviors of a two-dimensional mixed spin (1, 5/2) Ising Blume-Capel system under the influence sinusoidal magnetic fields have been analyzed within the framework of dynamic effective-field theory. The influences of the temperature, the single-ion anisotropy andthe frequency on dynamic hysteresis behaviors are investigated in detail. We also observe that the hysteresis loop area is very sensitive to changes in frequency. Besides, we have performed a comparison with the dynamic mean-field calculation in order to point out the effects of correlationsand found that some of the dynamic multiple hysteresis loop disappeared.
