We have clarified that the internal magnetic field in α-Mn is suppressed by pressure and that a first-order phase transition occurs at around 1.4–1.5 GPa by zero-field nuclear magnetic resonance. In the pressure-induced ordered state above about 1.4 GPa, the scenario of the canted-antiferromagnetic order or the ferrimagnetic order seems to be preferable to account for the weak ferromagnetism.

α-Mn 高压下内磁场的突然抑制

我们已经阐明，α- Mn中的内部磁场被压力抑制，并且通过零场核磁共振在 1.4-1.5 GPa 附近发生一阶相变。在大约 1.4 GPa 以上的压力诱导有序状态下，倾斜反铁磁有序或亚铁磁有序的情况似乎更适合解释弱铁磁性。
