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)-, ...
Giant electric field controlled magnetic anisotropy in epitaxial BiFeO3-CoFe2O4 thin film heterostructures on single crystal Pb(Mg1/3Nb2/3)(0.7)Ti0.3O3 substrate
(AIP Publishing, 2011-07-01)
We have deposited self-assembled BiFeO3 (BFO)-CoFe2O4 (CFO) thin films on Pb(Mg1/3Nb2/3)(0.7)Ti0.3O3 (PMN-PT) substrates and studied the change in magnetic anisotropy under different strain conditions induced by an applied ...
Shear-mode magnetostrictive/piezoelectric composite with an enhanced magnetoelectric coefficient
(AIP Publishing, 2012-05-01)
A magnetoelectric (ME) laminate heterostructure consisting of two shear-mode piezoelectric Pb(Mg1/3Nb2/3)O-3-30PbTiO(3) (PMN-PT) single crystal layers, a longitudinally magnetized magnetostrictive Tb0.3Dy0.7Fe1.92 alloy ...
Geometry-induced magnetoelectric effect enhancement and noise floor reduction in Metglas/piezofiber sensors
(AIP Publishing, 2012-08-01)
The geometry-dependent magnetoelectric (ME) effect was theoretically and experimentally investigated for multi-push-pull mode Metglas/Pb(Zr,Ti)O-3 sandwich-like laminates. Such structures hold promise for passive sensor ...
Ultralow equivalent magnetic noise in a magnetoelectric Metglas/Mn-doped Pb(Mg1/3Nb2/3)O-3-PbTiO3 heterostructure
(AIP Publishing, 2012-07-01)
An ultralow equivalent magnetic noise of 6.2 pT/root Hz at 1 Hz was obtained in a bimorph heterostructure sensor unit consisting of longitudinal-magnetized Metglas layers and a transverse-poled 1 mol. % Mn-doped ...
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 ...
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 ...
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 ...
Nonlinear magnetoelectric response of a Metglas/piezofiber laminate to a high-frequency bipolar AC magnetic field
(AIP Publishing, 2013-03-01)
A nonlinear magnetoelectric (ME) response has been investigated in a Metglas/piezofiber laminate by applying a bipolar AC magnetic field (H-ac) without a DC magnetic bias. The ME voltage (V-ME) was measured for various ...
Conformal miniaturization of domains with low domain-wall energy: Monoclinic ferroelectric states near the morphotropic phase boundaries
(American Physical Society, 2003-11-07)
A theory is developed for intermediate monoclinic (FEm) phases near morphotropic phase boundaries in ferroelectrics of complex oxides. It is based on the conformal miniaturization of stress-accommodating tetragonal domains ...
