A systematic study of the structural, dielectric and piezoelectric behaviour of the lead-free system (0.94-x) Na 0.5 Bi 05 TiO 3 -0.06BaTiO 3 -xK 0.5 Na 0.5 NbO 3 exhibiting giant piezo-strain was carried out as a function of composition (0.0 ≤ x ≤ 0.025), electric field and temperature. While x-ray diffraction revealed cubic structure for all the compositions, neutron diffraction patterns shows weak superlattice peaks characteristic of a √ 2 x √ 2 x 16 type modulation. The giant piezostrain is…
