NiCo nanoparticles-doped ZnO nano array and The Magnetic Properties
NiCo nanoparticles was uniformly doped on ZnO nanorod arrays by electroless polyol method. The effect of the deposition time (t) on the structure and magnetic properties has been investigated. The Ni-rich nanocomposition is detected when t <;30 min. The atomic ratio of Ni to Co is approaching to 1:1 when t increases to 60 min. In addition, NiCo-doped ZnO nanorods show typical superparamagnetic properties when t <; 30 min, while the ferromagnetic properties is more obvious when t increases to 60 min. The saturation magnetization (Ms) of the ZnO-CoNi nanocomposite is about 95 emu/g which is smaller than that of bulk Ni50Co50. It could be attributed to the oxidation of the surface of NiCo-ZnO nanocmposites.
