Effect of sintering temperature on leakage current of polycrystalline multiferroic DyFeO 3 system.

Effect of sintering temperature on the leakage current of polycrystalline multiferrioc DyFeO3material is reported. Samples were synthesized through Sol-Gel route. From the Rietveld refinement of X-Ray Diffraction (XRD) data it is observed that, samples were found to be of single phase. From the room temperature leakage current density study, it was observed that leakage current density decreases with increase of sintering temperature and Space charge limited conduction (SCLC) and Ohmic conduction mechanisms are dominant at lower and higher electric field values. The observations are corroborated in terms of microstructure changes with sintering temperature. [ABSTRACT FROM AUTHOR]
