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 ...
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 ...
Effect of intensive and extensive loss factors on the dynamic response of magnetoelectric laminates
(AIP Publishing, 2010-11-01)
We report the correlation between intensive and extensive losses in piezoelectric materials with the frequency dependent response of layered magnetoelectric (ME) composites. Three different piezoelectric compositions were ...
Dual-phase self-biased magnetoelectric energy harvester
(AIP Publishing, 2013-11-01)
We report a magnetoelectric energy harvester structure that can simultaneously scavenge magnetic and vibration energy in the absence of DC magnetic field. The structure consisted of a piezoelectric macro-fiber composite ...
Tunable self-biased magnetoelectric response in homogenous laminates
(AIP Publishing, 2012-12-01)
In this study, we demonstrate self-biased magnetoelectric effect in homogenous two-phase magnetostrictive-piezoelectric laminates. Our results illustrate the method for tuning the magnitude of self-bias effect and provide ...
Giant magnetoelectric coupling in laminate thin film structure grown on magnetostrictive substrate
(AIP Publishing, 2012-05-01)
Highly dense 1 mu m-thick piezoelectric film was deposited on magnetostrictive substrate [platinized nickel-zinc ferrite (NZF)]. A strong magnetic coupling between the piezoelectric film and magnetostrictive NZF substrate ...
Self-biased converse magnetoelectric effect
(AIP Publishing, 2011-11-01)
In this letter, we investigate the direct magnetoelectric (DME) and converse magnetoelectric (CME) effects in three-phase metal-ceramic laminate composites. Longitudinally poled and transversely magnetized (L-T) laminate ...
Large piezoresistivity phenomenon in SiCN-(La,Sr)MnO3 composites
(AIP Publishing, 2009-02-01)
We present the results on SiCN-(La,Sr)MnO3 (LSMO) composites correlating the observed large piezoresistance behavior with the microstructural features and defect chemistry. Scanning electron microscopy characterization ...
Using transient shear rheology to determine material parameters in fiber suspension theory
(AIP Publishing, 2009-05-01)
Fiber suspension theory model parameters for use in the simulation of fiber orientation in complex flows are, in general, either calculated from theory or fit to experimentally determined fiber orientation generated in ...
