Magnetic structure of Co(Cr0.925Fe0.075)2O4

We report results of neutron diffraction (ND) measurements on Co(Cr0.925Fe0.075)2O4 compound and determination of its magnetic structure. ND data at 90 K shows ferrimagnetic structure which is consistent with the bulk magnetization transition temperature, TC (~ 120 K). Appearance of additional peaks at 20 K coincides with the view that a magnetostructural transition occurs at TS (~ 26 K) in bulk magnetization of the sample.
