通过准确的全势密度泛函方法预测，闪锌矿（ZB）CrSb相是一种坚固的半金属（HM）铁磁体，每个公式的磁矩为3.000mu（B）。其 HM 能隙达到 0.774 eV，并且即使压缩 21% 仍保持非零。由于ZB CrSb相是尚未通过实验实现的三种ZB相中最好的（也是所有ZB过渡金属磷族化物中最好的）并且与III-V半导体兼容，因此其优异的重模铁磁性应该在自旋电子学和其他应用中有用。
It is predicted with the accurate full-potential density-functional method that the zinc blende (ZB) CrSb phase is a robust half-metallic (HM) ferromagnet with a magnetic moment of 3.000mu(B) per formula. Its HM gap reaches 0.774 eV and persists to be nonzero even when it is compressed by 21%. Because the ZB CrSb phase is the best of the three ZB phases that have yet been realized experimentally (and also the best of all ZB transition-metal pnictides) and compatible with the III-V semiconductors, its excellent HM ferromagnetism should be useful in spin electronics and other applications.
