        Synthesis and ferroelectric behavior of Gd doped BNT ceramics

        Vijayeta Pal,R.K. Dwivedi,O.P. Thakur 한국물리학회 2014 Current Applied Physics Vol.14 No.1

        In the present work, polycrystalline (Bi1xGdx)0.5Na0.5TiO3 (BGNT) ceramics with low amount of rare earth ion Gd3þ (x ¼ 0, 0.02, 0.03, 0.04) have been synthesized by a semiewet technique. XRD patterns show single phase formation for all the samples with a rhombohedral structure at room temperature. FESEM images show decrease in grain size with Gd concentration. The temperature dependence of dielectric constant has revealed that the depolarization temperature ‘Td’ decreases with increasing x and the temperature ‘Tm’ of maximum dielectric constant increases initially for x ¼ 0.02 thereafter decreases. All the samples have shown saturated hysteresis (PeE) loop at room temperature. The BGNT ceramic system for composition, x ¼ 0.02 exhibits improved piezoelectric properties and strong ferroelectricity. With increasing temperature, polarization has been found to be reduced and deformed PeE loops are observed around ‘Td’.
