DC Electrical Properties of Antimony Substituted Lithium Ferrites

Abstract

This paper discusses the DC electrical properties of antimony substituted lithium ferrites with compositional formula [Li0.5+x SbxFe2.5-2x O4]; where x=0.0 to 1.0 insteps of 0.1 prepared by conventional standard ceramic method sintered at1200 oC. It has been studied by means of compositional and temperature dependent resistivity in the range of 303-773K. It is found that the Neel’s temperatures, increase up to x=0.3 then decrease up to x= 0.5 then again increase and maintain a constant. The resistivity of the samples is found found in the range between 104 -109Ω-cm at room temperature. The activation energies were calculated in ferromagnetic and paramagnetic regions and are found to lie in between 0.02 and 0.4 eV. They are found to be decreasing up to x=0.2 then increase to x=0.4 further decrease to x=0.9 finally increase at x=1.0 with continuous increases of antimony. It shows that these belong to semiconductor materials. The polaran radius and jump length were also calculated. The polaran radius is increases up to x=0.3 then gradually increases with continuous increase of antimony concentration. The conduction mechanisms were studied using polaran radius and it is confirmed that conduction mechanism takes place between Fe2+ and Fe3+.
