Abstract

Ferrous antimonite, FeSb₂O₄, which is isostructural with Pb₃O₄, and some lead- and cobalt-doped variants of composition FeSb_1.5Pb_0.5O₄ and Co_0.5Fe_0.5Sb_1.5Pb_0.5O₄ have been examined by ⁵⁷Fe and ¹²¹Sb Mössbauer spectroscopy. Antimony is present as Sb³⁺. The presence of Pb²⁺ on the antimony site induces partial oxidation of Fe²⁺ to Fe³⁺. There is no Verwey-type transition in which electrons are shared between iron in different oxidation states. The quasi-one-dimensional magnetic structure gives rise to situations in which weakly coupled Fe²⁺ ions can coexist in a non-magnetic state alongside Fe³⁺ ions in a magnetically ordered state.
