Triclinic phase in tilted (001) oriented BiFeO3 epitaxial thin films
(AIP Publishing, 2009-03-01)
We report a triclinic phase in perovskite BiFeO3 (BFO) epitaxial thin films grown on (130) and (120) oriented SrTiO3 substrates. The lattice constants of the BFO thin films changed with tilt of the substrates from (001) ...
Polarization switching in (001)-oriented Pb(Mg1/3Nb2/3)O-3-x%PbTiO3 crystals: Direct observation of heterogeneous nucleation by piezoreponse force microscopy
(AIP Publishing, 2004-11-01)
Polarization switching in (001)-oriented Pb(Mg1/3Nb2/3)O-3-x%PbTiO3, PMN-x%PT, crystals for x=20 and 35 has been investigated in situ by scanning force microscopy in a piezoresponse mode, under a step-increased dc electrical ...
Fragile phase stability in (1-x)Pb(Mg1/3Nb2/3O3)-xPbTiO(3) crystals: A comparison of 001 and 110 field-cooled phase diagrams
(American Physical Society, 2006-05-09)
Phase diagrams of  and  field-cooled (FC) (1-x)Pb(Mg1/3Nb2/3O3)-xPbTiO(3) or PMN-xPT (0.15 <= x <= 0.38) crystals have been constructed, based on high-resolution x-ray diffraction data. Comparisons reveal several ...
Dynamic origin of the morphotropic phase boundary: Soft modes and phase instability in 0.68Pb(Mg(1/3)Nb(2/3)O(3))-0.32PbTiO(3)
(American Physical Society, 2008-09-04)
We report neutron inelastic scattering and high-resolution x-ray diffraction measurements on single crystal 0.68Pb(Mg(1/3)Nb(2/3)O(3))-0.32PbTiO(3)) (PMN-0.32PT), a relaxor ferroelectric material that lies within the ...
