  The dynamic phase transition has been studied in the two dimensional kinetic
Ising model in presence of a time varying (sinusoidal) magnetic field by Monte
Carlo simulation. The nature (continuous or discontinuous) of the transition is
characterized by studying the distribution of the order parameter and the
temperature variation of the fourth order cumulant. For the higher values of
the field amplitude, the transition observed is discontinuous and it is
continuous for lower values of the field amplitude, indicating the existence of
a tricritical point (separating the nature of the transition) on the phase
boundary. The transition is observed to be a manifestation of stochastic
resonance.
