Abstract

<jats:p>Synchrotron X-rays on the Swiss Norwegian Beamline and BM28 (XMaS) at the ESRF have been used to record the diffraction response of the PMN–PT relaxor piezoelectric 67% Pb(Mg<jats:sub>1/3</jats:sub>Nb<jats:sub>2/3</jats:sub>)O<jats:sub>3</jats:sub>–33% PbTiO<jats:sub>3</jats:sub>as a function of externally applied electric field. A DC field in the range 0–18 kV cm<jats:sup>−1</jats:sup>was applied along the [001] pseudo-cubic direction using a specially designed sample cell for<jats:italic>in situ</jats:italic>single-crystal diffraction experiments. The cell allowed data to be collected on a Pilatus 2M area detector in a large volume of reciprocal space using transmission geometry. The data showed good agreement with a twinned single-phase monoclinic structure model. The results from the area detector were compared with previous Bragg peak mapping using variable electric fields and a single detector where the structural model was ambiguous. The coverage of a significantly larger section of reciprocal space facilitated by the area detector allowed precise phase analysis.</jats:p>
