High Field Magnetoresistance in MnP

Abstract

The transverse magnetoresistances of high purity single crystals of MnP have been measured at a temperature of 1.5 K in applied magnetic field up to 80 kOe. The magnetoresistance exhibits sharp minima for the magnetic field along the b and c axes, which suggests the existence of cylindrical Fermi surfaces perpendicular to the a axis, in consistency with previous experiments. The Shubnikov-de Haas-like oscillation with a frequency of 1.7×10⁵ G is observed in the a axis resistivity under the b axis magnetic field.
