Tetragonal and cubic CuFe2O4 are prepared and studied by Mössbauer‐effect technique at room temperature and at 4.2 K with and without applied strong magnetic fields. The cation distributions and the hyperfine parameters are determined and compared with magnetization measurements. The results show that tetragonal CuFe2O4 is an inverse spinel of Néel collinear arrangement of spins and that cubic copper ferrite is not completely inverse with a cation distribution dependent on the heat treatment.
