Abstract: 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 β∕ν=0.143±0.004 and γ∕ν=1.766±0.036, respectively. The obtained critical exponents show that present magnetic system belongs to same universality class with the two-dimensional equilibrium Ising model. Finally, we present dynamic phase diagram separating dynamically ordered phase from the disordered phase.
