Self-assembled NaNbO3-Nb2O5 (ferroelectric-semiconductor) heterostructures grown on LaAlO3 substrates
(AIP Publishing, 2012-09-01)
We deposited NaNbO3 (NNO)-Nb2O5 (NO) self-assembled heterostructures on LaAlO3 (LAO) to form ferroelectric-semiconductor vertically integrated nanostructures. The NNO component formed as nanorods embedded in a NO matrix. ...
Giant strain with ultra-low hysteresis and high temperature stability in grain oriented lead-free K0.5Bi0.5TiO3-BaTiO3-Na0.5Bi0.5TiO3 piezoelectric materials
(Springer Nature, 2015-02-26)
We synthesized grain-oriented lead-free piezoelectric materials in (K0.5Bi0.5TiO3-BaTiO3-xNa(0.5)Bi(0.5)TiO(3) (KBT-BT-NBT) system with high degree of texturing along the [001]c (c-cubic) crystallographic orientation. We ...
Alternating and direct current field effects on the structure-property relationships in Na0.5Bi0.5TiO3-x% BaTiO3 textured ceramics
(AIP Publishing, 2013-06-01)
The influence of alternating (ac) and direct current (dc) fields on the structural and dielectric properties of [001](PC) textured Na0.5Bi0.5TiO3-7%BaTiO3 (NBT-7%BT) ceramics has been investigated. X-ray diffraction ...
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) ...
Multiferroic properties of modified BiFeO3-PbTiO3-based ceramics: Random-field induced release of latent magnetization and polarization
(American Physical Society, 2005-09-28)
It has been found that aliovalent-substituted BiFeO3-PbTiO3-based polycrystalline materials have significantly enhanced multiferroic properties. Relative to unmodified BiFeO3, our results for modified BiFeO3-PbTiO3-based ...
Resonant bending mode of Terfenol-D/steel/Pb(Zr,Ti)O-3 magnetoelectric laminate composites
(AIP Publishing, 2006-09-01)
Resonant bending-mode Tb1-xDyxFe2-y/elastic-steel/Pb(Zr,Ti)O-3 magnetoelectric (ME) laminate composites have been investigated. An elastic-steel layer with a relatively high Q(m) significantly increases the resonant ...
Fe-Ga/Pb(Mg1/3Nb2/3)O-3-PbTiO3 magnetoelectric laminate composites
(AIP Publishing, 2005-11-01)
We have found large magnetoelectric (ME) effects in long-type laminate composites of Fe-20% Ga magnetostrictive alloys and piezoelectric Pb(Mg1/3Nb2/3)O-3-PbTiO3 single crystals. At lower frequencies, the ME voltage ...
Monoclinic M-C vs orthorhombic in 001 and 110 electric-field-cooled Pb(Mg1/3Nb2/3O3)-35%PbTiO3 crystals
(AIP Publishing, 2006-02-01)
Structural phase transformations in Pb(Mg1/3Nb2/3O3)-35%PbTiO3 crystals with an electric field (E) applied along [110] and [001] directions have been performed by x-ray diffraction. In the field-cooling process, a phase ...
Extremely low frequency response of magnetoelectric multilayer composites
(AIP Publishing, 2005-03-01)
A promising generation of extremely low frequency magnetic field sensors, based on multilayer composites (MLCs) of magnetostrictive Terfenol-D, (Tb(1-x)Dy(x)Fe(2-y)) and piezoelectric Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3), has ...
The influence of Mn substitution on the local structure of Na0.5Bi0.5TiO3 crystals: Increased ferroelectric ordering and coexisting octahedral tilts
(American Institute of Physics, 2012-03-15)
The ferroelectric domain structure of pure Na1/2Bi1/2TiO3 (NBT) and 1 at.% Mn-doped NBT (Mn-NBT) crystals was investigated by piezoresponse force microscopy. The correlation length of the polar regions was found to increase ...
