Glycine acts as the complexing agent for Co2+ and was effective in avoiding the precipitation of Co(OH)2. The Co-Ce-O films prepared had a smooth surface. The Co content in the deposited films was subject to change from 0 to 100 vol.%, depending on the concentration of the CoSO4 in the reaction solution. Coercivity and sheet resistivity decrease suddenly at 22 vol.% Co. Therefore, the nano-size structure of the films may be changed at this concentration 关键词: atomic force microscopy;cerium compounds;cobalt;coercive force;discontinuous metallic thin films;electrical resistivity;electrodeposition;electrodeposits;ferromagnetic materials;magnetic thin films;nanostructured materials;surface structure;X-ray diffraction;X-ray photoelectron spectra;metal-oxide ferromagnetic granular films;metal-oxide coelectrodeposition;simultaneous deposition;complexing agent;smooth surface;sheet resistivity;coercivity;nanosize structure;X-ray diffraction;XPS;atomic force microscopy;magnetization curves;surface morphology;Co-CeO2
