Abstract
(K1-xNax)NbO3 (KNN) is especially paid attention to as a lead-free piezoelectric material. It is known that KNN has a morphotropic phase boundary (MPB) at $x\sim 0.5$, which shows a high piezoelectric property. However, it has not been fully clarified how the domain structure of KNN changes by applied electric field. In this study, we observed electric field-induced strain and domain fraction change of KNN films by synchrotron X-ray diffraction.
