Low Temperature Phase Transition in Sr(0.66)Ba(0.34)Nb2O6 single Crystal Fibers
J. L. B. Faria, C. W. A. Paschoal, P. T. C. Freire +5
The structural changes in Sr(0.66)Ba(0.34)Nb2O6 single crystal fibers when the temperature decreases from 295 to 10 K is investigated by dielectric constant measurements and Raman…

A Raman Investigation of PbZr0.94Ti0.06O3 Ceramics Under High-Pressures
A. G. Souza Filho, P. T. C. Freire, J. M. Sasaki +5
We have investigated the behavior of the PbZr(0.94}Ti(0.06)O3 Raman spectra as a function of Hydrostatic pressures. The new structural phases were identified based on previous work…
