包覆型复合超微颗粒磁性材料研究

Study on Ultrafine Composite Magnetic Materials with Coating Structure

包覆型磁性微颗粒兼具复合材料多组分间的协同效应与核-壳型的包覆结构,可实现多功能和产生不同于原单一组分的新功能。本文主要叙述了包覆型复合超微磁性颗粒的结构特征、磁电特性与高频电磁特性,并介绍其制备方法和研究现状,最后分析特性参数可调的包覆型磁性超微粒的研究前景。

Magnetic particles with coating structure have co-operation effect among the compositions and interface, which gives rise to multi-functions and novel phenomena different from that of single component. This paper shows their structural characteristics, electro-magnetic properties, and high-frequency properties, while we introduce their preparation methods and current development. Some research direction for the core/shell magnetic ultrafine particles with controllable properties is also proposed in the end.
