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…

The monoclinic phase of PZT ceramics: Raman and phenomenological theory studies
A. G. Souza Filho, K. C. V. Lima, A. P. Ayala +5
This work reports on the first Raman detection of the tetragonal to monoclinic phase transition in PZT ceramics near morphotropic phase boundary at low temperatures. The transition…
