Abstrakt: We succeeded in growing single crystals of an incongruent compound Cr3P with the noncentrosymmetric crystal structure by the Bridgman method using a sealed Mo crucible. The electronic specific heat coefficient γ is determined as 16 mJ=(K²·mol) from the specific heat measurement, which is mainly due to Cr-3d electrons. To clarify the Fermi surface properties, we carried out the de Haas-van Alphen (dHvA) experiment and detected several dHvA branches with the cyclotron effective masses of 1.1-3.6m0 (m0: rest mass of an electron). Each detected dHvA branch, which is well explained by the results of FLAPW energy band calculations, splits into two branches, reflecting the noncentrosymmetric crystal structure.
