Electrical and mechanical properties of samarium barium copper oxalate crystals

Abstract

30-32Samarium barium copper oxalate (SmBaCuOx) crystals were grown using silica gel technique by the diffusion of a mixture of samarium chloride, barium chloride and cuprous nitrate into the test tube having the set gel containing oxalic acid. The grown crystals were characterized by X-ray diffraction analysis, Inductively Coupled Plasma Atomic Emission analysis and microhardness measurements. The variation of dielectric constant εɼ and dielectric loss D in the frequency range100Hz - 1MHz has been studied and reported. The electrical conductivity of SmBaCuOx crystals was found to increase with increase of frequency
