Doping effect on the phase transition temperature in ferroelectric SrBi sub(2-x)Nd sub(x)Nb sub(2)O sub(9) layer-structured ceramics: a micro-Raman scattering study

The temperature dependence of Raman spectra for SrBi sub(2-x)Nd sub(x)Nb sub(2)O sub(9) ceramics (x from 0 to 0.2) has been studied in a wide temperature range from 80 to 873K. It is found that the peak position of the A sub(1g)[Nb] phonon mode at 207cm super(-1), which is directly associated with t...
