In this article, characteristics of the clamp-type cubic anvil high pressure cell, developed exclusively for neutron diffraction measurements, are presented. This pressure cell is extremely useful for magnetic studies that require a large volume of single crystal due to weak signal. Using the pressure cell, high pressure neutron diffraction measurements were performed using a single crystal of MnP, which exhibits superconductivity around 8 GPa. We could successfully observe magnetic Bragg peaks from Mn moments with 0.25 Bohr magneton at 7.5 GPa and 3 K.
