Özet

We have elucidated the dynamic phase transition features and finite-size scaling analysis of the kinetic Ising model on a triangular lattice system under the presence of a square-wave magnetic field. It has been found that as the value of half-period of the external field reaches its critical value, whose location is estimated by means of Binder cumulant, the system presents a dynamic phase transition between dynamically ordered and disordered phases. Moreover, at the dynamic phase transition point, finite-size scaling of the Monte Carlo results for the dynamic order parameter and susceptibility give the critical exponents beta/nu = 0.143 +/- 0.004 and gamma/nu = 1.766 +/- 0.036, respectively. The obtained critical exponents show that present magnetic system belongs to same universality class with the two-dimensional equilibrium !sing model. Finally, we present dynamic phase diagram separating dynamically ordered phase from the disordered phase. (C) 2018 Elsevier B.V. All rights reserved.
