Polarization rotation via a monoclinic phase in the piezoelectric 92%PbZn1/3Nb2/3O3-8%PbTiO3

Autor: Noheda, B., Cox, D. E., Shirane, G., Park, S-E., Cross, L. E., Zhong, Z.

Publikováno v: Phys. Rev. Lett. 86, 3891 (2001)

The origin of ultrahigh piezoelectricity in the relaxor ferroelectric PbZn1/3Nb2/3O3-PbTiO3 was studied with an electric field applied along the [001] direction. The zero-field rhombohedral R phase starts to follow the direct polarization path to tet

Stability of the monoclinic phase in the ferroelectric perovskite PbZr(1-x)TixO3

Autor: Noheda, B., Cox, D. E., Shirane, G., Guo, R., Jones, B., Cross, L. E.

Publikováno v: Phys. Rev. B 63, 014103

Recent structural studies of ferroelectric PbZr(1-x)TixO3 (PZT) with x= 0.48, have revealed a new monoclinic phase in the vicinity of the morphotropic phase boundary (MPB), previously regarded as the the boundary separating the rhombohedral and tetra

The monoclinic phase in PZT: new light on morphotropic phase boundaries

Autor: Noheda, B., Gonzalo, J. A., Guo, R., Park, S. -E., Cross, L. E., Cox, D. E., Shirane, G.

A summary of the work recently carried out on the morphotropic phase boundary (MPB) of PZT is presented. By means of x-ray powder diffraction on ceramic samples of excellent quality, the MPB has been successfully characterized by changing temperature

Origin of the high piezoelectric response in PbZr(1-x)TixO3

Autor: Guo, R., Cross, L. E., Park, S-E., Noheda, B., Cox, D. E., Shirane, G.

Publikováno v: Phys. Rev. Lett., 84 (2000) 5423

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 phase boundary, MPB) have shown that for both rhombohedral and tetrago

Report

A monoclinic ferroelectric phase in the Pb(Zr1-xTix)O3 solid solution

Autor: Noheda, B., Cox, D. E., Shirane, G., Gonzalo, J. A., Cross, L. E., Park, S-E.

Publikováno v: Appl. Phys. Lett. 74 (14), 2059-2061, 1999

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 measurements. At ambient temperature the sample has tetragonal symmetry (at= 4.
