RAMAN SCATTERING FROM AMORPHOUS STATE OF FERROELECTRIC PbTiO3 AND ITS CHANGE IN THE CRYSTALLIZATION PROCESS
T. Nakamura, M. Takashige et Y. AikawaI S.S.P., Univ. of Tokyo, Japan.
Abstract
Amorphous state of PbTiO3 has been prepared. DTA, optical and electron-microscopic investigations has clarified the crystallization temperature and the devitrification phenomenon. In Raman spectra, low-lying response is found in-the amorphous state, and the ferroelectric soft mode is found when it is crystallized.
