A series of soft ferrites with the general formula MgCrxFe2−xO4, where x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5, have been fabricated using the powder metallurgy route. The comprehensive study of Cr-doped magnesium ferrite has been carried out employing different techniques. The structural, surface, elemental, magnetic and dielectric properties have been examined using x-ray diffractometry, Fourier infrared spectroscopy, scanning electron microscopy, a vibrating sample magnetometer and an inductor capacitor resistor meter, respectively. The formation of a single-phase cubic spinel structure is confirmed by x-ray diffractometry and Fourier transform infrared spectroscopy. It is revealed that the lattice constant decreases with increasing Cr content. The surface of these samples consists of nano-particles in the range of 90–175 nm, while energy dispersive x-ray spectroscopy has been subject to elemental analysis of all the samples. The saturation magnetization and remanence has a nonlinear trend with increasing Cr content, while the coercivity decreases monotonically. The dielectric properties also confirm the formation of spinel ferrites.
