Evolution of domain structures in Na1/2Bi1/2TiO3 single crystals with BaTiO3
(American Physical Society, 2011-02-16)
The domain structures of Na1/2Bi1/2TiO3-BaxTiO3 (NBT-x%BT) crystals for x = 0, 4.5, and 5.5 have been investigated by polarized light and piezoresponse force microscopies. The results show that BaTiO3 (i) refines the size ...
Evidence for anisotropic polar nanoregions in relaxor Pb(Mg1/3Nb2/3)O-3: A neutron study of the elastic constants and anomalous TA phonon damping in PMN
(American Physical Society, 2012-09-18)
We use neutron inelastic scattering to characterize the acoustic phonons in the relaxor Pb(Mg1/3Nb2/3)O-3 (PMN) and demonstrate the presence of a highly anisotropic damping mechanism that is directly related to short-range ...
Effect of uniaxial stress on the large-signal electromechanical properties of electrostrictive and piezoelectric lead magnesium niobate lead titanate ceramics
(American Institute of Physics, 2004-02-15)
The electromechanical performance characteristics of electrostrictive 0.9 Pb(Mg1/3Nb2/3)O-3-0.1 PbTiO3 and piezoelectric 0.7 Pb(Mg1/3Nb2/3)O-3-0.3 PbTiO3 ceramics have been investigated under uniaxial stress (sigma). The ...
