The Fe-doped CuO nanopowder was synthesized by following the standard solid-state reaction method.The structure and magnetic properties of the Fe-doped CuO nanopowder were investigated.X-ray diffraction spectra confirmed the monoclinic structure of CuO and no secondary phase was detected,indicating that the Fe ions were incorporated into CuO.The ferromagnetism in Fe-doped CuO was studied and is believed to originate from the interaction between Fe ions and Cu ions via a super-exchange interaction or F-center mediated exchange interaction.
