Electronic structure of MnP

The manganese phosphide, MnP, is a typical 3d intermetallic compound. The authors report a self-consistent APW calculation of the spin-polarised energy band structure for MnP. A one-electron potential is constructed by the local-spin-density approximation. For a minority spin electron, bands near the Fermi energy, EF, consist mainly of Mn d states and have a high density of states. Bands for a minority spin electron have a low density of states at EF. The calculated results for the total density of states satisfactorily explain the UPS spectrum and the electronic specific heat. The calculated spin moment per formula is 1.2 mu B and is in good agreement with the experimental value of 1.3 mu B.
