Monoclinic structure of unpoled morphotropic high piezoelectric (PbMg1/3Nb2/3O3)0.65-(PbTiO3)0.35 and (PbZn1/3Nb2/3O3)0.91-(PbTiO3)0.09 compounds
J-M. Kiat, Y. Uesu, B. Dkhil +3
Evidences of a monoclinic phase in unpoled (PbMg1/3Nb2/3O3)1-x-(PbTiO3)x with x=0.35 (PMN-PT 35%) and unpoled (PbZn1/3Nb2/3O3)1-x-(PbTiO3)x with x=0.09 (PZN-PT 9%) are presented fr…
Symmetry of high-piezoelectric Pb-based complex perovskites at the morphotropic phase boundary II. Theoretical treatment
Yasusada Yamada, Yoshiaki Uesu, Masaaki Matsuda +4
The structural characteristics of the perovskite- based ferroelectric Pb(Zn1/3Nb2/3)O3-9%PbTiO3 at the morphotropic phase boundary (MPB) region (x≃0.09) have been analyzed. T…
Symmetry of high-piezoelectric Pb-based complex perovskites at the morphotropic phase boundary I. Neutron diffraction study on Pb(Zn1/3Nb2/3)O3 -9%PbTiO3
Yoshiaki Uesu, Masaaki Matsuda, Yasusada Yamada +4
The symmetry was examined using neutron diffraction method on Pb(Zn1/3Nb2/3)O3 -9%PbTiO3 (PZN/9PT) which has a composition at the morphotropic phase boundary (MPB) between Pb(Zn1/3…
Universal Phase Diagram for High-Piezoelectric Perovskite Systems
D. E. Cox, B. Noheda, G. Shirane +3
Strong piezoelectricity in the perovskite-type PbZr(1-x)TixO3 (PZT) and Pb(Zn1/3Nb2/3)O3-PbTiO3 (PZN-PT) systems is generally associated with the existence of a morphotropic phase…
