Systematic Investigation of Dynamic Magnetic Phase Transitions Using the Path Probability Method. III. Mixed-Spin (3/2,7/2) Blume-Capel Ising System on a Square Lattice under an Oscillating Magnetic Field
Path probability analysis reveals dynamic phase transitions in mixed-spin square lattices, highlighting how oscillating fields and crystal fields govern nonequilibrium states.
Key Points
To systematically analyze the dynamic magnetic properties, phase transitions, and compensation behavior of an interpenetrating square lattice mixed-spin (3/2, 7/2) Blume-Capel Ising model subjected to a time-dependent oscillating magnetic field.
Applied the path probability method to determine dynamic magnetizations and stationary magnetization oscillations in a mixed-spin (3/2, 7/2) Blume-Capel Ising system.
Constructed nonequilibrium dynamic phase diagrams across varied crystal-field interactions, oscillating magnetic field amplitudes, and both ferrimagnetic and ferromagnetic exchange couplings.
Identified dynamically ordered and disordered phases demarcated by both first- and second-order dynamic phase transition boundaries, as well as dynamic tricritical points.
Observed coexistence regions and P-, Q-, R-, S-, and N-type compensation behaviors in the ferrimagnetic regime, while W- and M-type behaviors were absent.
Demonstrated that increasing crystal-field interactions stabilizes the dynamically ordered phase, whereas greater magnetic-field amplitude induces dynamic disorder, with ferromagnetic coupling producing simpler topologies devoid of compensation.
