A Mossbauer study of pentavalent iron in a vanadium(V) oxide matrix

摘要

The formation of iron in the 5+ oxidation state was observed in iron-doped vanadium(V) oxide: this state is characterised by a singlet with the isomer shift #delta# = -0.56 +- 0.01 mm s~(-1) relative to #alpha#-iron in the Mossbauer spectrum at room temperature.
