DYNAMIC HYSTERESIS FEATURES OF A MIXED SPIN (1/2, 3/2) ISING SYSTEM WITHIN THE PATH PROBABILITY METHOD

We examined the dynamic hysteresis features (DHFs) of a mixed spin 1/2 and 3/2 Isingsystem on a square lattice by using the path probability method (PPM) in the presence of atime-varying (sinusoidal) magnetic field. In this system, the PPM contains three rate constantsin which one of them ( 2 k ) corresponds to the wheel speed in the melt spinning method(MSM). In particular, we investigated the influences of reduced temperature (T), angularfrequency (ω), and the rate constant ( 2 k ) for the attractive bilinear interaction on the DHFs.In addition, we studied the magnetic coercive fields (CFs) and remanent magnetizations(RMs) versus T, ω and 2 k . We observed that some of our obtained results are in qualitativelygood agreement with some experimental studies on some magnetic materials and the DHFsobtained by using the MSM as well as some theoretical works, especially with various Isingsystems.
