The effect of a transverse tensile stress on the electric-field-
induced 90-domain reorientation in tetragonal lead zirconate
titanate (PZT) near the morphotropic phase boundary was
investigated in situ using X-ray diffraction (XRD). The XRD
intensity ratio, I(002)/I(200), which represents the ratio of the
volume of the c-domains to that of the a-domains on the PZT
surface, was examined as a function of the electric field at
various stress levels. It was found that a transverse tensile
stress changes the electric-field dependence of I(002)/I(200),
