Structure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method
Author(s):
Abstract:
Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spherical shape. Specific surface area of the nanoparticles was between 27.47x104 cm2/g to 141.4x104 cm2/g which had been calculated by X-Ray Diffraction data. The magnetic measurements of nanoparticles were done at room temperature and found that nanoparticles exhibit a ferromagnetic behavior with different values of saturation magnetization and coercivity.
