摘要: Abstract The dynamic magnetic properties, such as phase transitions (DPTs) and diagrams (DPDs), are reported in 2-Dimensional (2D) kinetic spin-7/2 Ising system under an oscillating external field. With this aim mind, the Glauber type stochastic dynamics utilized to obtain mean-field equation determining system's motion on a square lattice. obtained is solved numerically. First, observe phases, average sublattice magnetization time variations investigated. After that, determine (first- or second-order) of DPTs DPTs, magnetizations' thermal behavior examined. Finally, DPDs calculated two different planes. contains paramagnetic (P), ferromagnetic-1/2 (F1/2), ferromagnetic-7/2 (F7/2) fundamental phases six mixed regions (or phases) well private points reentrant phenomena. It has been appeared that strongly dependent interaction parameters.
