Transition metal oxides constitute an interesting and widely investigated class of compounds in solid state and materials chemistry. They form the basis of solid state chemistry for the study of structure, composition and various physical and chemical properties that are not only of fundamental importance, but have technological applications. The important properties of these materials include superconductivity, ferromagnetism, magnetoresistance, half-metallicity, catalysis, nonlinear optical property, ferroelectri-city and multiferroic property all are of current immense interest.

The MR can simply be defined as change in electrical resistance of a material on application of an external magnetic field. Thus, MR can broadly be defined as the relative change in resistance of a material on application of magnetic field according to Equation 5.1
