| Abstract: | 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 ... |
