Abstract

Here we are reporting the structural, dielectric and ferroelectric properties of PLZFNT ceramic having compositional formula Pb₁ _-1.5xLa_xZr_0.588Ti _0.392Fe_0.01Nb_0.01O₃ (x = 0-0.02 in steps of 0.005). Samples were prepared by solid state route. The structural, dielectric and ferroelectric properties are studied as a function of La content. X-ray diffraction (XRD) analysis reveals pure perovskite tetragonal structure for all the compositions. There is drastic improvement in ferroelectric properties with La substitution. Ratio of remnant to spontaneous polarization (P_r/P_s) which indicates the measure of squareness of the PE loop is found to improve with the increase in La content.
