Description

The results of x-ray diffraction studies on 0.65Bi(Ni1/2Ti1/2)O3-0.35PbTiO3 solid solution poled at various electric fields are presented. After poling, significant value of planar electromechanical coupling coefficient (kP) is observed for this composition having cubic structure in unpoled state. The cubic structure of 0.65Bi(Ni1/2Ti1/2)O3-0.35PbTiO3 transforms to monoclinic structure with space group Pm for the poling field ≥5 kV/cm. Large c-axis microscopic lattice strain (1.6%) is achieved at 30 kV/cm poling field. The variation of the c-axis strain and unit cell volume with poling field shows a drastic jump similar to that observed for strain versus electric field curve in (1 − x)Pb(Mg1/3Nb2/3) O3-xPbTiO3 and (1 − x)Pb(Zn1/3Nb2/3)O3-xPbTiO3.
