| Abstract: | The magnetic structure of non-stoichiometric Fe1?xO was investigated by neutron scattering measurements on a quenched single crystal of Fe0.91O below the Néel temperature. In each defect cluster, there exist ferromagnetic moments and they are arranged antiferromagnetically with the periodicity of twice that of the atomic superstructure. Relation between the defect structure and the magnetic properties for a wide range of compositions was discussed. |
