dc.description.abstractSamples of Ba1.266Ti2.956 Fe7.6Li0.844O19 hexaferrite have been prepared using anatase and rutile phases of TiO2 by classical ceramic route. A pure sample of Ba Fe12O19 has also been prepared for comparison. The structural, electrical and magnetic characteristics have been studied by XRD, SEM, FTIR, two probe method, hysteresis loop and susceptibility curves. The samples exhibit hexagonal magnetoplumbic structure with spacegroup P63/mmc and p type ferrimagnetic behaviour. BaFe12O19 is a hard ferrite, however, the substituted hexaferrites are soft ferrites. The substitution causes increase in grain size and particle size. The Mc value, coercive force Hc, squareness MR/Ms and Curie temperature Tc are large for rutile TiO2 based samples as compared to anatase TiO2 based samples. However, the anatase allotrope based samples enhance the grain growth. These materials can be used in the applications related to magnetic recording, microwave absorption and EM absorption.en_US
