Structural, Optical and Magnetic Properties of Gd3+ Substituted Ni0.7Zn0.3Fe2O4 Ferrites
This study demonstrates that synthesizing Gd³⁺-substituted Ni₀.₇Zn₀.₃Fe₂O₄ ferrites via a sol-gel method yields spherical nanoparticles with a stable cubic spinel phase, an increased optical band gap, and enhanced soft magnetic characteristics with improved spin coherence.
