Abstract
ABSTRACT We studied the dynamic magnetic properties such as dynamic phase transitions, dynamic compensation temperatures, and dynamic phase diagrams in the spin-7/2 multilayer Ising system under an oscillating external magnetic field The system was simulated in the mean-field approximation using a Glauber type stochastic dynamic. The mean sublattice magnetizations’ time variations were examined to determine the system's dynamic phases. The thermal behavior of dynamic sublattice magnetizations was investigated to determine the type of dynamic phase transitions (first- or second-order) and to obtain the dynamic compensation temperatures. and type compensating behaviors were seen in various types of magnetization curves. The phase diagrams are calculated in and planes, for different values of the Hamiltonian parameters. The p, i, f1/2 , f7/2 , af7/2 , and af1/2 fundamental phases, as well as the i + p, i + f1/2 , af1/2 + p, af7/2 + p and i + af1/2 mixed phases. The system illustrated one, two, or three dynamic critical points (•) and E, TP, Z, and B special points.
