The magnetic ordering of the normal spinel ferrimagnet NiCr_2O_4 below T_C = 74K was reinvestigated by neutron scattering and magnetization measurements on a powder specimen. We found another magnetic transition at T_S = 31K besides T_C in both experiments. The ordering of a ferrimagnetic (longitudinal) component and that of an antiferromagnetic (transverse) component occur at T_C and T_S, separately. A new magnetic structure model of NiCr_2O_4 below T_S with a spontaneous magnetization of about 0.3 μ_B/formula is proposed based on experimental neutron scattering intensity.
