| 摘 要： | 动态磁谱参数,包括微波磁导率实部和虚部、截止频率等,与材料本征磁参数、结构形貌参数的制约关系,作为高频磁性材料性能的标杆和发展方向的理论指导,一直伴随着高频磁性材料的发展而不断演变,是动态磁化物理理论研究和磁性功能材料设计所关注的核心问题。磁结构决定了极限关系式的形式,而极限关系式为磁结构的设计、应用和发展提供了理论指导。该文综合介绍了近年来国内外高频磁结构和磁极限关系研究的发展情况,着重分析两者相辅相成的关系和研究方法,并归纳了该领域的发展趋势和存在的一些主要问题。

| Abstract: | Bounds relation between the dynamic magnetic parameters(e.g.the real and imaginary part of the microwave permeability,or the cutoff frequency) and the intrinsic magnetic parameters is a key issue for the high frequency magnetic structures.In the past decades,the bounds relation is developed with the fast development of high frequency magnetic structures,as the theoretical support of material design and the guidance of future development.This paper reviews the development and recent progress of both high fre... |
