A Moessbauer study of pentavalent iron in a vanadium(V) oxide matrix
Abstract
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 δ = -0.56±0.01 mm s-1 relative to α- iron in the Moessbauer spectrum at room temperature.
