Synthesis and magnetic properties of Co and Ni based nanostructures

In this work we present our experimental results on the synthesis and magnetic properties of cobalt and nickel based nanostructures. Co and Ni nanoparticles have been synthesized by polyol method and Co-Ni-P amorphous nanowire arrays have been synthesized by electrochemical deposition. The morphology and sizes of synthesized nanostructures were studied, by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Magnetic characteristics of the nanostructures were determined at room temperatures by using a vibrating sample magnetometer (VSM), in an external field of 15 kOe. The obtained Co and Ni nanoparticles present a superparamagnetic behaviour. The Co-Ni-P nanowire arrays present soft magnetic properties.
