Spontaneous symmetry breaking of domain walls in phase-competing regions
Hiroaki Ishizuka, Yasusada Yamada, Naoto Nagaosa
We study the nature of domain walls in an ordered phase in the phase-competing region of two Ising-type order parameters. Considering a two-component theory, we show that the…
A Theory of Ferroelectric Phase Transition in SrTiO induced by Isotope Replacement
Yasusada Yamada, Norikazu Todoroki, Seiji Miyashita
A theory to describe the dielectric anomalies and the ferroelectric phase transition induced by oxygen isotope replacement in SrTiO is developed. The proposed model gives consi…
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…
