在单相纳米晶Sm2Co17永磁体中发现了异常的晶体结构稳定性。室温下,Sm2Co17合金体系中存在三种晶体结构,即菱形th2zn17型(2:17 R)、六角形tbcu7型(1:7 H)和六角形th2ni17型(2:17 H)。从纳米晶合金中原子空间占位和子结构间的交换耦合的角度解释了单相Sm2Co17合金中磁性能对结构特征的强烈依赖性。在单相纳米晶Sm2Co17永磁体中发现了异常的晶体结构稳定性。室温下,Sm2Co17合金体系中存在三种晶体结构,即菱形th2zn17型(2:17 R)、六角形tbcu7型(1:7 H)和六角形th2ni17型(2:17 H)。从纳米晶合金中原子空间占位和子结构间的交换耦合的角度解释了单相Sm2Co17合金中磁性能对结构特征的强烈依赖性。
Abnormal crystal structure stability is discovered in the single-phase nanocrystalline Sm2Co17 permanent magnet. Three kinds of crystal structures, namely the rhombohedral Th2Zn17-type (2:17 R), the hexagonal TbCu7-type (1:7 H), and the hexagonal Th2Ni17-type (2:17 H), are claimed to exist at room temperature in the Sm2Co17 alloy system. The strong dependence of the magnetic properties on the structure characteristics in the single-phase Sm2Co17 alloy is interpreted in view of the atom space occupancy and the exchange coupling between substructures especially in the nanocrystalline alloy.Abnormal crystal structure stability is discovered in the single-phase nanocrystalline Sm2Co17 permanent magnet.
