摘要：

The amorphous nickel hydroxide nanospheres have been prepared by a simple and green electrochemistry technique, and the magnetism measurements of the products show that the prepared amorphous nickel hydroxide nanospheres present ferromagnetism below the Curie temperature of 16.5 K, accompanied by high magnetization of 50 emu g(-1) and high coercivity of 630 Oe at 5 K. These findings pave a way to applications of amorphous nickel hydroxide nanostructures as magnetic materials.
