Die Auswirkung des eingeprägten Nachwirkungsfeldes auf die Bewegung ferroelektrischer Domänenwände in Seignettesalzkristallen

Abstract

Dielectric dispersions at low and audio frequencies and ferroelectric after effects in Rochelle Salt are due to ordering of point defects as recently has been shown byUnruh and the author. It is possible to describe all these effects in terms of an intrinsic electric field. This paper deals with the influence of the intrinsic field on the motion of ferroelectric domain walls. Preliminary measurements are consistent with the conception of the intrinsic field, but some details are to understand only by the assumption of permanent imperfections of the crystals.
