Origin of the high piezoelectric response in PbZr(1-x)TixO3
R. Guo, L. E. Cross, S-E. Park +3
High resolution x-ray powder diffraction measurements on poled PbZr(1-x)TixO3 (PZT) ceramic samples close to the rhombohedral-tetragonal phase boundary (the so-called morphotropic…
Charge Ordering and Phase Competition in the Layered Perovskite Lasr2mn2o7
D. N Argyriou, H. N. Bordallo1, B. J. Campbell +6
Charge-lattice fluctuations are observed in the layered perovskite manganite LaSr2Mn2O7 by Raman spectroscopy as high as 340 K and with decreasing temperature they become static an…
A tetragonal-to-monoclinic phase transition in a ferroelectric perovskite: the structure of PbZr(0.52)Ti(0.48)O3
B. Noheda, J. A. Gonzalo, L. E. Cross +4
The perovskite-like ferroelectric system PbZr(1-x)Ti(x)O3 (PZT) has a nearly vertical morphotropic phase boundary (MPB) around x=0.45-0.50. Recent synchrotron x-ray powder diffract…
A monoclinic ferroelectric phase in the Pb(Zr1-xTix)O3 solid solution
B. Noheda, D. E. Cox, G. Shirane +4
A previously unreported ferroelectric phase has been revealed on a highly homogeneous sample of Pb(Zr0.52Ti0.48)O3 by high-resolution synchrotron x-ray powder diffraction measureme…
