Abstract

The high strain response of {001} oriented Bi0.5Na 0.5TiO3-7BaTiO3-2K0.5Na 0.5NbO3 is ascribed to a pseudocubic to tetragonal electric-field-induced phase transformation. Using in situ electric field dependent x-ray diffraction the macroscopic strain response can be reconstructed from the observed peak shift and peak bifurcation due to phase transformation. A volume averaging of the lattice strain of Bi0.5Na 0.5TiO3-7BaTiO3-2K0.5Na 0.5NbO3 estimates a maximum macroscopic strain response of 0.65% compared to 0.48% from macroscopic measurements.
