Keywords:
Magnetoplumbite, Hexaferrites, electrical conductivity, Seebeck coefficient etc.Abstract
A new compound of Lithium hexaferrites with general chemical formula Li0.5Fe 0.5+x Al12-2xCoxO19 where x= 2,3,4,5 and 6, were synthesized by standard ceramic technique using stoichiometric proportion. The lattice parameters ofthe multicrystalline materials have been determined and characterized by X-ray diffraction technique. XRD data shows the formation of samples of a single phase hexagonal M-type ferrites with a space group P63/mmc(194). The electrical conduction was carried out over the temperature range from 270C- 8000 C. The electrical conduction in the ferrites was explained on the basis of Vervway models. A Seebeck study reveals that all samplesare N-type semiconductors.
