Rietveld Refinement, Cation Distribution, and Magnetic Properties of Gd3+‐Substituted Co0.5Zn0.5Fe2−xO4 Spinel Ferrite Nanoparticles
Gadolinium‐substituted cobalt–zinc spinel ferrite nanoparticles, Co0.5Zn0.5GdxFe2−xO4 (x = 0.00–0.10), were synthesized by the sol–gel autocombustion method and calcined at 700 °C for 5 h. Rietveld refinement of X‐ray diffraction data confirmed a single‐phase cubic spinel structure (space group Fd3¯m) up to x = 0.08. A...
