摘要

利用蒙特卡罗模拟研究了振荡磁场中 Ising 核壳纳米粒子的动态磁特性。研究了随时间变化的磁场、交换耦合、晶体场、浓度和温度对系统瞬时磁化的影响。此外，还研究了动态磁滞行为。结果表明，该系统在低温下表现出弛豫行为，这种行为受到各种参数的影响，并随着温度的升高而明显减弱。

Dynamic magnetic properties of core-shell nanoparticles in an oscillating magnetic field

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.
