The samples of Cr 3 + substituted Nickel ferrite with composition NiCr X Fe 2-X O 4 were synthesized by employing sol gel auto combustion method. The ferrite powder materials were subjected to X-ray diffraction spectroscopy (XRD) analysis and Transmission electron microscopy (TEM) analysis for the study of structural as well as morphological characteristics. The X-ray diffraction pattern at the room temperature showed the formation of a cubic spinel ferrite having a single phase. Moreover, the values of lattice parameters (a) counter verified the same. TEM imaging demonstrated the formation of nanosize particles and the presence of all constituent elements were confirmed by energy dispersive X-ray (EDAX) analysis. Vibrating Sample Magnetometer (VSM) was used to study the magnetic properties of the samples. The magnetic properties showed low saturation magnetization (Ms), Remnance (Mr) as well as Coercivity (Hc). This confirmed the viability of such materials in the various applications of such as water treatment, microwave device materials, permanent magnets and storage recording devices.
