Phonon transport in an initially twisted polyvinyl acetate nanofiber
(AIP Publishing, 2013-05-01)
A reduction in phonon thermal conductivity enhances thermoelectric performance. One method to accomplish this is by applying mechanical stress to a nanostructure. We consider an initially twisted 20 nm polyvinyl acetate ...
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 ...
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 ...
High magnetic field sensitivity in Pb(Zr,Ti)O(3)-Pb(Mg(1/3)Nb(2/3))O(3) single crystal/Terfenol-D/Metglas magnetoelectric laminate composites
(American Institute of Physics, 2010-05-01)
We report the magnetic field sensitivity results on five layer structure given as Metglas/Terfenol-D/PMN-PZT/Terfenol-D/Metglas, where PMN and PZT correspond to Pb(Mg(1/3)Nb(2/3))O(3) and Pb(Zr,Ti)O(3), respectively. The ...
Giant magnetoelectric torque effect and multicoupling in two phases ferromagnetic/piezoelectric system
(American Institute of Physics, 2011-11-15)
The physical mechanism of a non-magnetostrictive magnetoelectric (ME) effect was revealed and designated as the ME torque (MET) effect. Experimental results showed that the MET effect could be huge; a simple MET device ...
Mechanical loss and magnetoelectric response in magnetostrictive/interdigitated-electrode/piezoelectric laminated resonators
(American Institute of Physics, 2013-03-28)
The mechanical quality factor and the resonant magnetoelectric (ME) response of multi-push-pull mode Metglas/interdigitated (ID)-electrode/Pb(Zr,Ti)O-3 (PZT) ME resonators have been studied as a function of ID-electrode ...
Design and characterization of broadband magnetoelectric sensor

In this study, we present a broadband magnetoelectric (ME) sensor design comprising of Metglas and piezoelectric ceramic laminate composite. A systematic study was conducted to elucidate the role of various composite ...
Theoretical model for geometry-dependent magnetoelectric effect in magnetostrictive/piezoelectric composites
(American Institute of Physics, 2012-06-15)
A quasistatic theoretical model including geometry effect is presented for predicting the magnetoelectric (ME) coefficients in a ME multilayer composite consisting of magnetostrictive and piezoelectric layers. The model ...

We report results on a dimensionally gradient magnetoelectric (ME) sensor that demonstrates high performance over a wide frequency range and a magnetic dc bias operating in the longitudinal-transversal mode. The design of ...
Magnetoelectric effect in crystallographically textured BaTiO3 films deposited on ferromagnetic metallic glass foils
(American Institute of Physics, 2011-02-01)
We demonstrate a significant control of the polarization response under an applied magnetic field for a magnetoelectric (ME) heterostructure. This structure was comprised of a 2 mu m thick ferroelectric BaTiO3 (BTO) film ...
