Effect of Cr³⁺ Doping on Magnetic Properties of Zn-Mg Ferrite Nanoparticles

Magnetochemistry, 2023
Zn0.6Mg0.4CrxFe2−xO4 (0 ≤ x ≤ 0.4) nanoparticles were synthesized using a hydrothermal technique. The obtained magnetic nanoparticles (MNPs) exhibited a spinel structure, where the lattice constant decreased with the Cr3+ ion content.
