Effect of Rare Earth Lanthanides Doping on the Magnetic Properties of Magnesium Nanoferrite Prepared via Sol–gel Route

This study investigates the synthesis and magnetic properties of rare earth (RE) lanthanides-doped magnesium nanoferrite. Specifically, the chemical composition MgCexEryFe2−x−yO4 (where x = 0.4, 0.6, 0.8 and y = 0.6, 0.4, 0.2) was synthesized by sol–gel method. The series that was synthesized underwent characterization through X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The samples were examined by means of a superconducting quantum interference device (SQUID) magnetometer. M-H curves plotted at 300, 100, 20, and 5 K. The results demonstrate that doping with RE ions (specifically Ce3+ and Er3+) effectively controls their properties of samples. These research works are significant for the advancement of communication technology in the future.
