Strain response to sinusoidal electric field. a Sinusoidal electric field, E, demonstrated for the 1 Hz measurement; b 200pc peak position, 2θ; c intensities of 111pc/11\(\bar 1\)pc reflections, and calculated d 200pc lattice strain, ε200; and e non-180° 111pc domain texture, f111. The error bars arise from profile fitting using Gaussian peak functions on individual single and double peaks. The dashed line is used here to indicate amplitude of electric field at ~0.5 s for the 1 Hz electric field
