MnP shows an interesting magnetic phase diagram under pressure up to ~7.5 GPa, where magnetic long range order disappears and superconductivity appears. Polarized neutron analyses were applied to two different helical magnetic structures (helical-c and helical-b). Helicity was observed in the both structures. The two helical domain ratio becomes more unbalanced in the helical-b structure at a higher pressure, suggesting that the Dzyaloshinskii-Moriya interaction, which is enhanced by a local structural strain, could be related with the helical structures.
