Abstract: A magnetochemical study of sodium ferrate samples obtained by heating sodium peroxide and iron(III) oxide at about 480 °C and in a 10:1 molar ratio of sodium to iron has shown that there exists a phase of iron in a higher oxidation state which, in terms of quenched orbital magnetism theory, can be considered as a high-spin oxocomplex of tetravalent iron, which is antiferromagnetic with a Neel temperature of about 14 K.
