Resistivity-thermo power co-relation derived temperature dependent transport behaviour of Mn(x)Zn(1-x)Fe(2)O(4) nanoparticles

Abstract

Nanoparticles of ferrite materials comprising the metal ions of Manganese and Zinc were chemically synthesized by co-precipitation method. The designated ferrite X- ray diffraction peaks and characteristic ferrite absorption bands in furrier transform infra-red absorption spectra confirmed spinel formation. Determination of full width at half maximum values of X-ray diffraction peaks and the corresponding calculations using Scherer formula suggested creation of nano grains. Micrograph obtained on Transmission Electron Microscope authenticated nano dimensions of the particles. Deviations in characteristic resistivity and thermo power values in response to ambient sample temperature variations were experimentally observed and used for co-relation derived temperature dependent transport behaviour analysis. Samples with concentration x= (0.8&1.0) showed high thermo power values at reasonably low temperatures with moderate specific resistance.
