Studies of the magnetic structure of Fe3P

Abstract
Magnetization, Mossbauer and neutron diffraction measurements have been made on powdered and single crystal samples of Fe3P. The average moments on the iron sites are 2.12 mu B, 1.25 mu B and 1.83 mu B. The Mossbauer spectra indicate a splitting of the moments of approximately 0.1 mu B for the atoms on each iron site. The observed magnetic hyperfine fields are 28.4 T and 27.3 T for FeI, 17.3 T and 17.5 T for FeII and 23.0 T and 25.0 T for FeIII at room temperature.
