摘　　要：磁性纳米粒子组装颗粒膜的电磁输运特性一直是凝聚态物理领域的研究热点之一.以原位组装的策略制备磁性颗粒膜,可以将磁性纳米粒子的制备和薄膜的组装过程分开,实现磁性颗粒膜中颗粒尺寸、颗粒间距等微结构要素的独立调控,为揭示磁性颗粒膜电磁输运特性的微观机制创造条件.本文总结了近年来磁性纳米粒子组装颗粒膜的制备及其电磁输运特性的主要研究成果,包括磁性颗粒膜的可控制备、电阻温度依赖性、导电机制,以及磁性颗粒膜的反常霍尔效应和标度理论.The electromagnetic transport properties of magnetic nanoparticle-assembled granular films have been one of the research hotspots in the field of condensed matter physics.Through in situ assembly of the magnetic granular films can separate the preparation of magnetic nanoparticles from the assembly of thin films,individual control of microstructure parameters has been realized,such as particle size and intergranular gap,so as to reveal the microscopic mechanism of electromagnetic transport properties of magnetic granular films.This review summarizes the main research results concerning the preparation of magnetic nanoparticle-assembled granular films and their electromagnetic transport properties,including the controllable preparation of magnetic granular films,resistance temperature dependence,electron conduction mechanism,anomalous Hall effect and the scaling theory of magnetic granular films.
