Description A nano-crystalline spinel ferrite (NC-SF) composites were synthesized using the standard ceramic method and were analyzed by several analytical techniques. The XRD characterization validates the production of a cubic spinel arrangement. Furthermore, XRD analysis showed that the bond length and ionic radii enlarge on A-sites and reduce slightly on B-sites with the increase in the content of Mn-Ti. Moreover, XRD analysis revealed that the crystallite size of Cd-Ti-Al-Mn lies in the range of 22.83-24.44nm. Additionally, the porosity of the Cd-Ti-Al-Mn ferrite samples reduces with increasing the content of Mn-Ti. The FT-IR spectra show one high-frequency band and three low-frequency bands in the range of 400-600 cm-1. The grain size was observed by SEM images to be uniformly distributed and lies within the range of ~0.66-1.18μm. The DC resistivity of the ferrite composite became greater with increasing the content of Mn-Ti. Moreover, the composite behaves electrically as semiconductor. The investigated Cd-Ti-Al-Mn ferrite composites exhibited current controlled negative resistance (CCNR) type of electrical switching characteristics at room temperature. The value of the switching electric field was noted to enlarge with the increase in the content of Mn-Ti. Additionally, there was no ageing observed for electrical switching property in the investigated ferrite composites
