摘　　要：交换弹簧现象在近几年是国际、国内的研究热点,取得了很大的进展,其中硬磁/软磁交换弹簧多层膜是很有价值的磁性材料。详细叙述了硬磁/软磁交换弹簧多层膜的理论和实验进展,着重讨论了硬磁/软磁交换弹簧多层膜的构造和原理,以及硬磁/软磁交换弹簧多层膜的用途,如巨磁致伸缩、永磁体、磁电阻等。The exchange springs constitute an important class of magnetic materials with high potential for practical applications and theoretical interest. In recent years, they have become a new and fascinating research area worldwide and obtained prodigious progress. This paper describes the up-to-date development of experiments and theories in the research of exchange springs formed in magnetic multilayers, discusses intensively the configuration and physical properties of hard/soft exchange springs. The hard/soft exchange springs exhibit various applications such as giant magnetostrictive materials, permanent magnets with giant maximum energy density and magnetoresistance.
