Abstract

The effect of the dipolar interaction strength on the dynamical hysteresis behavior of the nanodisk is investigated within the Heisenberg model and Monte Carlo simulation. The system is under the effect of the dynamical periodic sinusoidal magnetic field. It has been shown that dipolar interaction strength can induce dynamical phase transition and the transition from the fully dynamically ordered ground state to the weak dynamically ordered ground state. Besides, it has been shown that rising dipolar interaction raises the hysteresis loop area for higher temperatures and a linear relationship between the peak positions of the hysteresis loop area and the temperature locations of the peaks obtained.
