Inhomogeneous magnetic structure of the spinel ZnO8FeO2Cr2Se4
Sadykov R. A., Zaritskii V. N., Fradkov V. A.
Neutron-diffraction and magnetic studies of powdered Zn0.8FeO 2Cr2Se4 show that at low temperatures (Г<50 К) this compound has an inhomogeneous magnetic structure. This structure is formed by small ferrimagnetic clusters (L<80 A) whose size depends on the temperature.
