“…The scheme of the spectrometer (Fig. 2) is described by Gureva et al (2022). Application of the diffraction method at angles close to 180 has shown high sensitivity to changes in the crystal structure under the influence of an external electric field (Gureva et al, 2020).…”

“…Recently, the use of XRD at Bragg angles close to 90 has been proposed for determining piezoelectric coefficients, which allows one to add to the spatial locality of piezoelectric property magnitude measurement a better accuracy due to the high sensitivity to the relative variations in the lattice parameter up to 10 À6 -10 À7 (Gureva et al, 2020(Gureva et al, , 2022.…”

An in situ study of the spatial distribution of the piezoelectric properties of an LiNb(1−x)Ta x O3 crystal (〈x〉 = 0.088) in an external DC electric field was performed by the method of X-ray diffraction of synchrotron radiation at angles close to 180°. The variation of the d 22 piezoelectric coefficient was determined with high accuracy (up to 2%) in local areas by the angular shift of the diffraction maximum under the action of the electric field (E = 1582 V mm−1) applied on the crystal along the Y axis, during scanning along the X and Z directions. A correlation between the piezoelectric strain amplitude and the concentration of tantalum obtained by X-ray fluorescence mapping has been established.
