Magnetic Properties of Y3Fe5O12 Nanoparticles Doped Bi and Ce Ions

Y_2.9-xCe_0.1Bi_xFe₅O₁₂ (x = 0-0.5) nanoparticles ranging from 58 to 63 nm were fabricated by a sol-gel method, and their crystallite structures and magnetic properties were investigated by X-ray diffraction (XRD), IR spectroscopy, and vibrating sample magnetometer (VSM). Results of VSM show that the saturation magnetization intensity increased with increase in Ce content (0.1), decrease in Bi concentration (x), and increase in particle size of the formulation.
