Dynamic phase transition properties for the mixed spin-(1/2, 1) Ising model in an oscillating magnetic field

• Dynamic behaviors of a ferrimagnetic mixed spin (1/2, 1) Ising system are studied.
• We examined the effects of the Hamiltonian parameters on the dynamic behaviors.
• The phase diagrams are obtained in (T-h) plane.
• The dynamic phase diagrams exhibit the dynamic tricritical and reentrant behaviors.

Herein we study the dynamic phase transition properties for the mixed spin-(1/2, 1) Ising model on a square lattice under a time-dependent magnetic field by means of the effective-field theory (EFT) with correlations based on Glauber dynamics. We present the dynamic phase diagrams in the reduced magnetic field amplitude and reduced temperature plane and find that the phase diagrams exhibit dynamic tricitical behavior, multicritical and zero-temperature critical points as well as reentrant behavior. We also investigate the influence of frequency (ω) and observe that for small values of ω the mixed phase disappears, but for high values it appears and the system displays reentrant behavior as well as a critical end point.
