Effect of electric fields and mechanical stresses on switching and domain structure realignment in NaH3(SeO3)2crystals

Abstract
The domain structure of NaH3(SeO)2)-crystals has been studied with the aid of Barkhausen effect technique connected with visual optical observations. On this basis the peculiaritied of both ferroelectric and ferroelastic domain structure realignment under the action of external electric fields and mechanical stresses are analyzed.
