TLDR
In this article, the depolarization behavior of ordered and disordered lead scandium-tantalate (PST) ceramics has been studied by Byer-Roundy and Chynoweth method.Abstract:
The depolarization behavior of ordered and disordered lead scandium-tantalate (PST) ceramics has been studied by Byer-Roundy and Chynoweth method. A sharp decrease of the spontaneous polarization takes place in a narrow temperature range very close to the Curie temperature Tc for the ordered PST materials. For the disordered PST materials, however, the depolarization takes place within a wide temperature range much lower than the temperature of maximum dielectric constant Tm. Evidence of microdomain activities has been observed in disordered materials. The reversible pyroelectric effect is discussed in terms of the micro-macro transition of the domains in disordered PST materials.read more
