We report results of neutron diffraction (ND) measurements on Co(Cr{sub 0.925}Fe{sub 0.075}){sub 2}O{sub 4} compound and determination of its magnetic structure. ND data at 90 K shows ferrimagnetic structure which is consistent with the bulk magnetization transition temperature, T{sub C} (~ 120 K). Appearance of additional peaks at 20 K coincides with the view that a magnetostructural transition occurs at T{sub S} (~ 26 K) in bulk magnetization of the sample.
