Magnetic Nanocomposite Material

Nayak, B B (2006) Magnetic Nanocomposite Material. PhD thesis.



The present work deals with synthesis of composite materials consisting of magnetic nanoparticles dispersed in a magnetic or nonmagnetic insulating matrix and a study of their transport and magnetic properties. Two types of composites: ceramic–ceramic and metal– ceramic have been synthesized using three different techniques, microwave refluxing, glassceramic and aqueous reduction. These techniques promote formation of composites at the nano level, which is one of the primary aims of this thesis. These techniques are highly versatile and can be used for the synthesis of a wide variety of materials. Moreover, synthesis of nanocomposites using these techniques has not been investigated in detail earlier and this forms the objective in using these techniques. In ceramic–ceramic system, the main magnetic material is manganite with a perovskite type structure. The manganites are of interest because they exhibit colossal magnetoresistance (CMR) behavior and enhancing the magnitude ...
