Abstract
The polycrystalline material Sr(Bi3.9-xNdxLa0.1)(Ti3.975Zr0.025)O15 with variation of neodymium content from 2.5 to 10 wt% was prepared by solid state method. XRD analysis indicated the formation of a single- phase orthorhombic structure. SEM analysis revealed the formation of plate like structure. It was also observed that with increase in the content of Nd, the values of Curie temperature (Tc) and dielectric constant (ε) were increased and the tolerance factor (t) decreased. It was found that the remnant polarization, piezoelectric charge and electromechanical coupling coefficients were increased up to certain extent of Nd doping and further increase of Nd content decreased.
