Dynamic compensation temperature in the mixed spin-1/2 and spin-3/2 Ising model in an oscillating field on alternate layers of hexagonal lattice

The dynamic behavior of a mixed spin-l/2 and spin-3/2 Ising model with a crystal-field interaction in the presence of a time-varying magnetic field on alternate layers of hexagonal lattice is studied by using the Glauber-type stochastic dynamics. We study time variations of the average magnetizations in order to find the phases in the systems, and the temperature dependence of the dynamic sublattice magnetizations and total magnetization to obtain the dynamic phase transition (DPT) points and dynamic compensation points, respectively, as well as to characterize the nature (continuous and discontinuous) of transitions. Dynamic phase diagrams are also calculated for both DPT points and dynamic compensation effects. According to values of Hamiltonian parameters, besides the paramagnetic (p), antiferromagnetic (af) and antiferrimagnetic (i) fundamental phases, the af + p, i + p and i + af mixed phases, and the compensation temperature or P- and L-types behavior in the Neel classification nomenclature exist in the system.
