在高达2.2GPa的高压下测量了α-Mn的热膨胀，以研究反铁磁不稳定性与磁体积效应之间的关系。结果表明，随着压力的增加，TN减小，自发体积磁致伸缩的幅度变小。α-Mn的反铁磁性在5GPa以下消失。
Thermal expansion of α-Mn has been measured at high pressures up to 2.2 GPa in order to examine the relation between the instability of antiferromagnetism and the magnetovolume effect. It is found that TN goes down and the magnitude of spontaneous volume magnetostriction becomes small as pressure increases. The antiferromagnetism of α-Mn is suggested as disappearing below 5 GPa.
