Direct measurement of magnetoelectric exchange in self-assembled epitaxial BiFeO3-CoFe2O4 nanocomposite thin films
(AIP Publishing, 2009-05-01)
We report the direct measurement of a magnetoelectric (ME) exchange between magnetostrictive CoFe2O4 nanopillars in a piezoelectric BiFeO3 matrix for single-layer nanocomposite epitaxial thin films grown on (001) SrTiO3 ...
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 ...
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 ...
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 ...
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 ...
Active vibration and structural acoustic control of shape memory alloy hybrid composites: Experimental results
(Acoustical Society of America, 1990-12-01)
Shape memory alloy hybrid composites have been shown both by analytical simulations and experiments to be effective adaptive materials for active vibration and structural acoustics control [Rogers and Robertshaw, Engineering ...
Design and characterization of broadband magnetoelectric sensor
(American Institute of Physics, 2009-05-01)
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 ...
Dimensionally gradient magnetoelectric bimorph structure exhibiting wide frequency and magnetic dc bias operating range
(American Institute of Physics, 2009-12-01)
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 ...
