本文用中子衍射法在低温恒温器中对MnAs粉末进行了研究，实验压力为13kbar，温度为4.2K。发现在12.6kbar压力下保持低温的正交相MnP型结构中，形成了传播矢量为τa= 0.125X2πXa的螺旋磁结构。
Powdered MnAs has been investigated by neutron diffraction in a pressure cryostat, at hydrostatic pressures up to 13 kbar and temperatures down to 4.2 K. It has been found that in the orthorhombic MnP type structure, which under pressure is retained at low temperature, a spiral magnetic structure with propagation vector τa= 0.125X2πXa∗at 12.6 kbar is formed.
