STUDY OF RAMAN SPECTRA FOR FERROELECTRIC TUNGSTEN BRONZE-TYPE CRYSTALS SBN AND KNSBN
|
Abstract:
The Raman spectra of Sr1-xBaxNb2O6(SBN) and (K1-yNay)z(Sr1-xBax)l-zNb2O6(KNSBN) crystals have been obtained and discussed based on the space group theory and lattice dynamics. It provides scientific basic for an improvement on SBN and KNSBN by ion doping.
