The effect of competition between the frequency of the field and the frequency of the spin flipping on the kinetics of Ising metamagnet
چکیده انگلیسی

We consider the effect of a variable representing the competition between the frequency of the field and the frequency of the spin flipping (Ω  ) on the dynamics of the metamagnetic Ising model in a cubic lattice under the presence of a time varying (oscillating) external magnetic field. The system is modelled with a formalism of master equation at a mean-field level. The time averaged staggered magnetization (MsMs) acts as the order parameter and divides temperature field plane into three regions: anti-ferromagnetic, paramagnetic and coexistence of anti-ferromagnetic and paramagnetic phases. It is observed that the topology of the dynamical phase diagram depends strongly on Ω as well as the ratio between interlayer and intralayer couplings.
