Summary: Mg0.5Ni0.5Fe2-xCrxO4 (x = 0.0, 0.2, 0.4, and 0.6) ferrites were synthesized using the solid-state reaction route. The synthesized materials' crystal structure, microstructure, crystallite size, magnetic and resistivity properties were measured using XRD, SEM, FT-IR spectroscopy, VSM, and DC electrical resistivity measurements. The results showed that the synthesis was efficient and resulted in improved crystallite sizes in a single-phase cubic spinel structure. The addition of chromium ions resulted in changes in lattice constant, crystallite size, saturation magnetization, remanent magnetization, and coercivity.
