采用高压热压法设计并制备了（SmCo 7/FeCo）/SmCo 5异质结构多元磁体。研究了高压热压缩和磁反转过程中SmCo 7/FeCo和SmCo 5相区的配位和相互作用行为。SmCo 5的引入可以提高磁体的矫顽力。当SmCo_5含量为30wt%时，（SmCo_7/FeCo）/SmCo_5异质结构磁体的磁性能最佳，磁电阻为10.3kG，矫顽力为6.0kOe，最大磁化强度为16.7MG Oe。
We have designed and prepared heterostructured (SmCo7/FeCo)/SmCo5multicomponent magnets by high-pressure thermal compression. The coordination and interaction behavior of SmCo7/FeCo and SmCo5phase regions during high-pressure thermal compression and magnetic reversal process were studied. The introduction of SmCo5can improve the coercivity of the magnet. The heterostructured (SmCo7/FeCo)/SmCo5magnet with 30 wt% SmCo5content shows optimal magnetic properties withMrof 10.3 kG,Hciof 6.0 kOe, and(BH)maxof 16.7 MG Oe.
