Dynamic phase transitions and compensation temperatures in the mixed spin-1 and spin-5/2 Ising system on alternate layers of a hexagonal lattice

摘要: Abstract The magnetic properties of the mixed spin-1 and spin-5/2 Ising system with a crystal-field interaction in presence time-varying oscillating external field on hexagonal lattice are studied using Glauber-type stochastic dynamics. is formed by alternate layers spins σ = 1 S=5/2. set mean-field dynamic equations obtained employing Master equation. These solved firstly, time variations average sublattice magnetizations investigated order to find phases system. Then, thermal behaviors total magnetization also obtain phase transition points compensation temperatures. From this investigation, nature (continuous discontinuous) transitions type behavior determined. diagrams presented for both absence temperatures nine different planes. It was found that exhibits five fundamental phases, which composed binary ternary combinations temperature or N-type Neel classification nomenclature.
