摘要

超顺磁性氧化铁纳米颗粒是一种潜在的新研究对象。粒子间的相互作用在决定磁性纳米粒子的整体磁性行为中起着重要的作用，特别是在偶极相互作用中。在本文中，我们合成了一个实际样品，然后应用原子自旋模型模拟研究了偶极相互作用对Fe3O4磁铁矿纳米颗粒磁性能的影响。

Effect of dipolar interaction on magnetic properties of magnetite nanoparticles system: a simulation study

Superparamagnetic iron oxide nanoparticles are a potential candidate for novel research. The inter-particle interactions play a signiﬁcant role in determining the overall magnetic behavior of a magnetic nanoparticle assembly, especially in dipolar interaction. In this paper, we have synthesized a practical sample and then applied an atomistic spin model simulation study with input parameters obtained from experimental measurements to investigate the influence of the dipolar interaction on the magnetic properties of Fe3O4 magnetite nanoparticles.
