A Low Frequency Mechanical Transmitter Based on Magnetoelectric Heterostructures Operated at Their Resonance Frequency
(MDPI, 2019-02-19)
Magneto-elasto-electric (ME) coupling heterostructures, consisting of piezoelectric layers bonded to magnetostrictive ones, provide for a new class of electromagnetic emitter materials on which a portable (area ~ 16 ...
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)-, ...
Modeling and the signal-to-noise ratio research of magnetoelectric sensors at low frequency
(AIP Publishing, 2007-10-01)
The authors have modeled magnetoelectric (ME) laminate sensor units by considering both the ME laminate and detection circuitry. Theory predicts and experiments confirm that the signal-to-noise ratio increases with increasing ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
