A comparative study on the magnetic properties of Fe-doped CuO nanopowders prepared by sol–gel and co-precipitation method

The Fe-doped CuO nanopowders (Cu 0.95Fe 0.05O) were prepared by the sol–gel and the co-precipitation methods. The effects of synthesis methods on the structure, magnetic property and exchange bias effect of Cu 0.95Fe 0.05O nanopowders were investigated. The microstructure and magnetic properties of...

Description
Summary:The Fe-doped CuO nanopowders (Cu 0.95Fe 0.05O) were prepared by the sol–gel and the co-precipitation methods. The effects of synthesis methods on the structure, magnetic property and exchange bias effect of Cu 0.95Fe 0.05O nanopowders were investigated. The microstructure and magnetic properties of the two types of nanopowders were characterized by X-ray diffraction and physics property measuring systems, respectively. It was found that the sol–gel method tended to lead the formation of CuFe 2O 4 phase, which dominated the magnetic behaviors of the sample; the co-precipitation tended to lead larger exchange bias field at low temperature in samples, comparing with sol–gel method.
