Effect of Cooling Rate on Dynamic Magnetic Hysteresis Loop Behaviors of Magnetic Materials by Using as a Model Mixed Spin (1, 3/2) Ising System Under an Oscillating Magnetic Field

Abstract

Various experimental methods are used to examine the effect of cooling rate on the magnetic properties of magnetic materials, such as melt spinning at different wheel speeds. To shed light on these experimental studies as a theoretical study, we used a mixed spin (1, 3/2) Ising system on a square lattice under an oscillating magnetic field within the path probability method. It is very advantageous to use the path probability method in such studies, because it explains the dynamic magnetic phase behaviors and dynamic hysteresis curves of the system depending on all system parameters, and one of the coupling parameters (\({k}_{2}\)) arising in this method corresponds to the wheel speed (rate constant) in the melt spinning method. In this study, dynamic hysteresis curves of a magnetic material were obtained for different \({k}_{2}\) parameters as well as other system parameters, namely reduced temperature, crystal field interaction, and angular frequency. In some magnetic materials, hard and soft magnetic hysteresis loop behaviors and single and multiple hysteresis loop behaviors have been obtained, which have been reported theoretically as well as experimentally. The results shed light on experimental workers who were unable to reach higher wheel speeds using the melt-spinning method.
