Gadolinium Substitutions Induced Changes in the Magnetic Properties and Dielectric Behavior of Zinc–Magnesium Ferrite Nanoparticles | Original Article

ABSTRACT:

This study examines the structural, magnetic, electrical, and dielectric characteristics of rare earth-doped nanocrystalline gadolinium were introduced to the spinel lattice and the characteristics changed. Comparing sol-gel and co-precipitation-prepared nanocrystalline nickel ferrite's application properties. Magnetic qualities were analyzed by Vibrating Sample Magnetometry (VSM), while electrical and dielectric properties were evaluated using Keithley electrometer and Impedance analyzer. Terbium and gadolinium substitutions expand unit cells, whereas samarium doping decreases nickel ferrite nanoparticle lattice parameter. Gadolinium and samarium doping reduce nickel ferrite particle size, whereas terbium doping increases it.
