MnP is a prototype 3d-itinerant magnet but still a compound under considerable study. This is based on the characteristic magnetic phases including the helical, cone, and fan structures and a variety of phase transitions with a Lifshitz tricritical point. The Fermi surface properties, however, have been scarcely studied. We have thus carried out a de Haas–van Alphen (dHvA) experiment using a high-quality single-crystal sample grown by the Sn-flux method. Many dHvA branches are observed, ranging from 2.8 × 106 to 9.45 × 107 Oe. The corresponding cyclotron effective masses are moderately heavy, 0.7 − 10m0 (m0: rest mass of an electron), reflecting itinerant Mn-3d electrons.
