Abstract
The Monte Carlo simulation is employed to study the dynamic magnetic properties of Ising core-shell nanoparticles in an oscillating magnetic field. The effects of time-dependent magnetic field, exchange coupling, crystal field, concentration, and temperature on the instantaneous magnetization of the system are presented. In addition, the dynamic hysteresis behaviors are investigated. According to the results, the system displays relaxation behavior at low temperatures, which is affected by various parameters, and reduced significantly with temperature increasing.
