Özet

Magnetic properties of the kinetic Ising system on sandwiched trilayer with square lattices are studied employing the mean-field theory based on Glauber-type stochastic dynamics. The top and bottom layers of sandwiched trilayer are composed of S or α-spins (S = α = ± 1/2) , while the middle layer is composed of σ-spins (σ = ± 1). First, we investigate the time-dependence behavior of order parameters to obtain the kinetic system's phases. After that, the thermal behavior of dynamic sublattice magnetizations is studied to obtain the dynamic phase transitions (DPTs) and to determine the type of DPTs. The kinetic system shows both first- and second-order phase transitions. In the plane of the magnetic field's amplitude and temperature, we present the dynamic phase diagrams. The kinetic system shows rich dynamic phase diagrams, which are strongly dependent on Hamiltonian parameters.
