Comparison of Magnetic and Electrical Properties of Manganese-Doped Cobalt Ferrite Nanoparticles

Cobalt ferrites have been regarded as one of the competitive candidates in diversified applications because of their tailored electrical and magnetic properties by tuning structural parameters with doping of transition and/or rare earth elements. To meet the ever-growing technological demands, varieties of new compositions of cobalt ferrites with diverse properties are continuously developed and produced through different synthetic routes across the globe and are made available to the consumers. In the recent past, three compositions of manganese-doped cobalt ferrite nanoparticles have been developed through a solid-state reaction route by using the planetary ball milling technique. In this chapter, a comparison on their novelty in respect of their magnetic and electrical properties is made to spot their possible applications. Besides, few suggestions have been put forwards for further investigations to meet the challenges in the days to come.
