Özet
The dynamic magnetic phase behavior of a mixed-spin (1, 7/2) Blume–Capel Ising system on a hexagonal lattice is investigated using the Path Probability Method (PPM) in the presence of a periodically oscillating magnetic field. The effects of the magnetic-field amplitude and crystal-field interaction on the dynamic order parameters and phase diagrams are examined systematically for both ferrimagnetic ((Formula presented) and ferromagnetic ((Formula presented) exchange regimes. Thermal variations in dynamic magnetizations are used to determine the phase-transition temperatures and the nature of the transitions. Dynamic phase diagrams constructed in the (Formula presented) and (Formula presented) planes reveal first-order and second-order dynamic phase transitions, tricritical points and parameter-dependent phase boundaries. Various Néel-type compensation behaviors are observed in the ferrimagnetic regime, whereas no compensation phenomenon occurs in the ferromagnetic case. The results demonstrate that competition among exchange interactions, crystal-field effects, thermal fluctuations and the oscillating magnetic field strongly influences the stability of the dynamically ordered phases and the topology of the phase diagrams. This study provides a systematic dynamic phase-diagram analysis of the mixed-spin (1, 7/2) Blume–Capel system on a hexagonal lattice within the PPM framework.
