Vertical Boundary at x ~ 0.11 in the Structural Phase Diagram of the La1-xSrxMnO3 System (0.08 <= x <= 0.125)
D. E. Cox, T. Iglesias, E. Moshopoulou +3
The structural phase diagram of the La1-xSrxMnO3 system in the compositional range 0.08 <= x <= 0.125 has been investigated by high-resolution synchrotron x-ray powder diffraction…
Polarization rotation via a monoclinic phase in the piezoelectric 92%PbZn1/3Nb2/3O3-8%PbTiO3
B. Noheda, D. E. Cox, G. Shirane +3
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 rho…
Stability of the monoclinic phase in the ferroelectric perovskite PbZr(1-x)TixO3
B. Noheda, D. E. Cox, G. Shirane +3
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), previou…
The monoclinic phase in PZT: new light on morphotropic phase boundaries
B. Noheda, J. A. Gonzalo, R. Guo +4
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 qualit…
