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 $C_{2 v}^{19} \to C_{2 v}^{\neq = 19}$ phase transition in…

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 PbZr $_{1 - x}$ Ti $_{x}$ O $_{3}$ ( $0.02 \leq x \leq 0.14$ ) ceramics performed at room temperature. The pressure depend…
