The hyperfine field spectra of magnetite ( ) have been investigated at 4.2°K (below the Verwey transition temperature TV) and at 300°K (above TV). The low temperature spectrum is composed of at least eight inequivalent “ferrous‐like” B‐site lines, eight “ferric‐like” B‐site lines, and eight ferric A‐site lines. The high temperature B‐site spectrum shows structure caused by anisotropic hyperfine fields. The small anisotropy found suggests either a d‐band width greater than the B‐site trigonal splitting or electron hopping between B sites with energy levels severely lifetime broadened.
