Pulsed Laser Deposition of BaTiO3 Thin Films on Different Substrates
(Hindawi Publishing Corporation, 2010)
We have studied the deposition of BaTiO3 (BTO) thin films on various substrates. Three representative substrates were selected from different types of material systems: (i) SrTiO3 single crystals as a typical oxide, (ii) ...
Influence of dc-bias on phase stability in Mn-doped Na0.5Bi0.5TiO3-5.6 at. %BaTiO3 single crystals
(AIP Publishing, 2009-10-01)
Mn-doped Na0.5Bi0.5TiO3-5.6 at. %BaTiO3 (Mn:NBT-5.6% BT) single crystals were grown by a top-seeded solution growth method. Tetragonal and rhombohedral phases were found to coexist in the as-grown condition. The dielectric ...
X-ray and neutron diffraction investigations of the structural phase transformation sequence under electric field in 0.7Pb(Mg1/3Nb2/3)-0.3PbTiO(3) crystal
(American Institute of Physics, 2004-08-01)
The structural phase transformations of 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) (PMN-30%PT) have been studied using x-ray diffraction (XRD) and neutron scattering as a function of temperature and electric field. We observe the ...
Thermal stability of magnetoelectric sensors
(AIP Publishing, 2012-04-01)
The effect of temperature on the equivalent magnetic noise floor of Metglas-Pb(Zr, Ti)O-3 (PZT) laminate magnetoelectric (ME) sensors has been investigated in the temperature range of -50 degrees C to 50 degrees C. In ...
Piezomagnetic strain-dependent non-linear magnetoelectric response enhancement by flux concentration effect
(AIP Publishing, 2013-04-01)
The non-linear magnetoelectric (ME) effect of Metglas/Pb(Mg1/3Nb2/3)O-3-PbTiO3 heterostructures has been studied. Such effect holds promise for modulation mode ME sensor applications that require no dc bias. The non-linear ...
Crystallographic direction dependence of direct current field induced strain and phase transitions in Na0.5Bi0.5TiO3-x%BaTiO3 single crystals near the morphotropic phase boundary
(AIP Publishing, 2012-10-01)
The crystallographic dependence of the DC electric (E) field induced strain and phase transition in Na0.5Bi0.5TiO3-5.6%BaTiO3 (NBT-5.6%BT) single crystals has been investigated. An induced transition between pseudocubic ...
Structure of (001)-, (110)-, and (111)-oriented Pb(Fe1/2Nb1/2)O-3 epitaxial thin films on SrRuO3-buffered SrTiO3 substrates
(Cambridge University Press, 2008-03-01)
We have studied the lattice structure of variously oriented lead iron niobate (PFN) thin films with thicknesses of 50 < t < 500 nm that were deposited by pulsed laser deposition (PLD). We have identified that (001)-, (110)-, ...
Neutron and x-ray diffraction study of cubic [111] field-cooled Pb(Mg1/3Nb2/3)O-3
(American Physical Society, 2007-08-01)
Neutron and x-ray diffraction techniques have been used to study the competing long- and short-range polar order in the relaxor ferroelectric Pb(Mg1/3Nb2/3)O-3 (PMN) under a [111] applied electric field. Despite reports ...
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. ...
Direct observation of the near-surface layer in Pb(Mg1/3Nb2/3)O-3 using neutron diffraction
(American Physical Society, 2004-11-19)
Spatially resolved neutron diffraction as a function of crystal depth in Pb(Mg1/3Nb2/3)O-3 reveals the presence of a distinct near-surface region where a strong distortion in the lattice exists. A dramatic change in both ...
