CuS:Ni flowerlike morphologies composed of nanosheets were fabricated by the solvothermal route with polyvinyl pyrrolidon as surfactant and ethylene glycol as solvent. The as-prepared CuS:Ni morphologies were characterized by means of X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The size of CuS:Ni flowerlike morphologies was about 2 and 5 mu m corresponding to the Ni doping concentration of 3.7 and 7.1 at.%, respectively. The thickness of the nanosheets changes with changing Ni doping. The magnetic properties of the CuS:Ni products have been investigated in detail. (C) 2010 Elsevier B.V. All rights reserved.
