| 摘 要： | Research on exchange-spring magnets has focused on the microstructures of the materials.However,research has seldom been concerned with the effect of magnetic properties of soft magnetic phase on the energy product of an exchangespring magnet.In this paper,a simple one-dimensional numerical simulation is used to investigate this effect in a Nd2Fe14Bbased exchange-spring magnet.The results reveal that the larger the anisotropy constant,the stronger the exchange coupling,and the higher the magnetization of the soft magnetic4 phase,the larger the energy product of an exchange-spring magnet.This provides evidence for choosing a soft magnetic phase in an exchange-spring magnet.
