Analytical interpretation of temperature dependent combined quadrupolar and magnetic hyperfine interaction in Fe2+ Fe3 2+(PO4)2(OH)2 (barbosalite)

E. Mattievich , N.V. Vugman , L.M.A. Diehl , J. Danon

Synthetic barbosalite Fe2+ Fe32+(PO 4)2(OH)2 measured between 4.2 to 295 K by Mössbauer Spectroscopy shows a magnetic phase transition at 162 K. The spectra presenting combined quadrupolar and magnetic hyperfine interactions are interpreted using an analytical method.
