Abstract

Ferroelectric, hysteresis, impedance spectroscopy parameters, AC conductivity, and piezoelectric properties in the ceramics of Pb _0.74K_0.52Nb₂O₆ and Pb _0.74K_0.13Sm_0.13Nb₂O₆ have been studied. X-ray diffraction study reveals single phase with the orthorhombic structure. The samples were characterized for ferroelectric and impedance spectroscopy properties from room temperature to 600°C. Cole-Cole plots(Z″ versus Z′) are drawn at different temperatures. The results obtained are analyzed to understand the conductivity mechanism in both the samples. The piezoelectric constant d₃₃ has been found to be 96 × 10^-12 C/N in PKN.
