摘要利用广角x射线散射技术，在沿晶片[001]方向外加电场（场强E达13 kV cm−1）的影响下，对PbMg1/3Nb2/3O3-28 mol.% PbTiO3固化液（001）单晶片进行了室温原位研究。结构变化归因于铁电修饰之间的可逆相变的固溶体在近电极区域约1mm深。近电极层的一部分（在E = 4.5 kV cm - 1时约占5vol .%，在13 kV cm - 1时约占15vol .%）从最初的菱形结构转变为另一种结构，很可能是单斜相Mb相。x射线摇摆曲线轮廓形状的变化提示了电场诱导相变在自适应x射线光学中的可能技术应用。
Abstract An (001) single-crystal plate of a solid solution of PbMg1/3Nb2/3O3-28 mol.% PbTiO3 was investigated by Wide-Angle X-ray Scattering techniques at room temperature in situ under the influence of an external static electric field (field strength E up to 13 kV cm−1) applied along the [001] direction of the wafer. Structural changes attributed to a reversible phase transition between ferroelectric modifications of the solid solution in a near electrode region of about 1 mm depth are found. Part of the near-electrode layer (of about 5 vol.% at E = 4.5 kV cm−1 and about 15 vol.% at 13 kV cm−1) transforms from the initial rhombohedral structure to another one, most probably, the monoclinic Mb phase. Changes of the profile shape of X-ray rocking curves suggest possible technical use of the electric-field induced phase transition for adaptive X-ray optics.
