Abstract
- Li<subscript>0.45</subscript>Ni<subscript>0.1</subscript>Mn<subscript>0.1</subscript>Fe<subscript>2.35</subscript>O<subscript>4</subscript> ferrite samples were prepared by microwave-sintering (MS) and conventional (CS) techniques. XRD studies have confirmed the single-phase spinel structure of the sample. The lattice constant was found to be 8.334 Å which is lower than that of the conventionally sintered (CS) sample. Upon microwave sintering, improved physical and electrical properties (like density, resistivity etc.) were obtained. A comparative study has been made on the dielectric behavior of samples processed by both techniques. The possible mechanisms are discussed. [ABSTRACT FROM AUTHOR]
