摘要
Tree-shaped nickel nanocrystals with long main trunk and highly ordered branches were prepared via electrolytic method in ethylene glycol solution. The morphology and structures of nanotrees of crystalline nickel can be controlled by the processing of the surfactant(PVP) and electrolytic voltage. Magnetic property measurements at room temperature indicated that the as-prepared nanotrees of crystalline nickel possess higher saturation magnetism(MS) and coercivity(HC) than those of corresponding bulk nickel materials.

The morphology and structures of nanotrees of crystalline nickel can be controlled by the processing of the surfactant (PVP) and electrolytic voltage. Magnetic property measurements at room temperature indicated that the as-prepared nanotrees of crystalline nickel possess higher saturation magnetism (M-S) and coercivity (H-C) than those of corresponding bulk nickel materials.
