A Raman Study of Morphotropic Phase Boundary in PbZr1-xTixO3 at low temperatures
K. C. V. Lima, A. G. Souza, A. P. Ayala +5
Raman spectra of PbZr1-xTixO3 ceramics with titanium concentration varying between 0.40 and 0.60 were measured at 7 K. By observing the concentration-frequency dependence of vibrat…
Electric Field Induced Phase Transition in KDP Crystal Near Curie Point: Raman and X-ray Scattering Studies
A. T. Varela, J. M. Sasaki, I. Guedes +5
X-ray scattering measurements are performed in order to verify % that the mechanism leading to the DC electric field induced phase transition in…
High-pressure Raman study of L-alanine crystal
A. M. R. Teixeira, P. T. C. Freire, A. J. D. Moreno +4
Pressure-dependent Raman scattering studies in the range 0.0 -- 32 kbar were carried out in L-alanine in order to investigate its external mode phonon spectra in relation to the ph…
Concentration-Pressure phase diagram for rich Zr PZT ceramics
A. G. Souza Filho, P. T. C. Freire, A. P. Ayala +6
This work reports on the systematic high pressure Raman studies in the PbZrTiO () ceramics performed at room temperature. The pressure depend…
