Fabrication and Magnetic Properties of Cobalt-Copper Nano-Composite

Co/Cu nano-composite was prepared by combustion method. The final product was characterized by X-ray diffraction (XRD). The different magnetic parameters of the as prepared composite were determined by using vibrating sample magnetometer (VSM). The investigated preparation method resulted to formation of CuO/CoO nano- composite. The results obtained showed that the values of saturation magnetization and the remnant magnetization of CuO/CoO nano-composite were found to be 6.75 and 1.97 emu/g, respectively. However, the value of the coercivity of the as prepared composite was 329.7 Oe. The crystal size of cobalt species involved in the as prepared composite decrease as the cobalt content increases.
