研究了单畴磁粒子通过交换和偶极相互作用相互作用的磁滞现象。通过蒙特卡罗模拟研究了纳米粒子阵列中晶粒尺寸分布、晶粒密度、各向异性能量和交换相互作用对磁性能的影响。我们还介绍了聚吡咯纳米复合体系的一些实验结果，这些结果与我们在模拟中观察到的趋势一致。
The hysteresis of an array of interacting single domain magnetic particles is studied, where the particles interact via exchange and dipolar interactions. The dependence of the magnetic properties on the distribution of grain sizes, the density of the grains, the anisotropy energy and the exchange interactions in the array is investigated through Monte Carlo simulations fornanoparticle systems. We also present some experimental results on the-polypyrrole nanocomposite system which agree with the trends observed in our simulations.
