Özet

This study provides a comprehensive investigation of dynamic magnetic hysteresis behaviors in a mixed-spin (3/2, 7/2) Blume-Capel Ising system on a two-dimensional square lattice utilizing the Path Probability Method (PPM). By systematically varying temperature, crystal field strength, field frequency, and kinetic rate constants, we examine how these parameters influence the morphology of dynamic magnetic hysteresis loops (DMHLs), coercive fields (CFs), and remanent magnetizations (RMs). Our results reveal diverse hysteresis loop types, including single, double, and triple loops depending on system conditions and exchange interactions (in both ferromagnetic and antiferromagnetic cases). Importantly, we demonstrate that the PPM captures kinetic effects overlooked in conventional models and provides insight into the dynamic magnetic response and hysteresis behavior of the system under an oscillating magnetic field. These findings exhibit qualitative consistency with previously reported theoretical results and experimentally observed trends in rapidly processed magnetic materials. The work makes a significant contribution to the design of functional magnetic materials with tunable dynamic properties.
