On the Peculiar Types of Ferroelectric Domain in Rochelle Salt Crystals

Abstract

In rochelle salt crystals a peculiar type of ferroelectric domain (as Fig. 2) is observed around a hole which is filled with saturated solution. Another peculiar type of domain (as Fig. 3) is observed around a group of fine crystals which has been crystallized by a certain treatment. These peculiar types of domain are understood to result from stress concentration around the hole and the group of fine crystals.
