Abstract

Rietveld analysis of Bragg intensities from in-situ neutron powder diffraction of nearly stoichiometric Mn 0.9990 0 reveals the presence of several percent Mn interstitials. Similar to isostructural Fe1−x 0, the cation interstitials are tetrahedrally coordinated in the rocksalt structure (Fm3m).
