Giant self-biased magnetoelectric coupling in co-fired textured layered composites
(AIP Publishing, 2013-02-01)
Co-fired magnetostrictive/piezoelectric/magnetostrictive laminate structure with silver inner electrode was synthesized and characterized. We demonstrate integration of textured piezoelectric microstructure with the ...
High thermal stability of piezoelectric properties in (Na0.5Bi0.5TiO3)(x)-(BaTiO3)(y)-(Na0.5K0.5NbO3)(1-x-y) ceramics
(AIP Publishing, 2013-01-01)
We report the piezoelectric and ferroelectric properties of (Na0.5Bi0.5TiO3)(x)-(BaTiO3)(y)-(Na0.5K0.5NbO3)(1-x-y) ceramics for Na0.5K0.5NbO3 rich end of composition (x, y <= 0.04 mol. %). These compositions were found to ...
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 ...
Defect and adsorbate induced ferromagnetic spin-order in magnesium oxide nanocrystallites
(AIP Publishing, 2012-05-01)
We report the correlation between d(0) ferromagnetism, photoluminescence (PL), and adsorbed hydrogen (H-) species in magnesium oxide (MgO) nanocrystallites. Our study suggests that the oxygen vacancies, namely singly ionized ...
Ferroelectric properties and dynamic scaling of < 100 > oriented (K0.5Na0.5)NbO3 single crystals
(AIP Publishing, 2011-06-01)
In this letter, we report the dielectric and ferroelectric (FE) characteristics of potassium sodium niobate (K0.5Na0.5NbO3) single crystals grown by flux method. Orientation analysis of as-grown cubical-shaped crystals was ...
Ultra-high frequency photoconductivity decay in GaAs/Ge/GaAs double heterostructure grown by molecular beam epitaxy
(AIP Publishing, 2013-03-01)
GaAs/Ge/GaAs double heterostructures (DHs) were grown in-situ using two separate molecular beam epitaxy chambers. High-resolution x-ray rocking curve demonstrates a high-quality GaAs/Ge/GaAs heterostructure by observing ...
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 ...
Giant energy density in 001 -textured Pb(Mg1/3Nb2/3)O-3-PbZrO3-PbTiO3 piezoelectric ceramics
(AIP Publishing, 2013-01-01)
Pb(Zr,Ti)O-3 (PZT) based compositions have been challenging to texture or grow in a single crystal form due to the incongruent melting point of ZrO2. Here we demonstrate the method for achieving 90% textured PZT-based ...
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 ...
Direct and converse effect in magnetoelectric laminate composites
(AIP Publishing, 2011-06-01)
In this letter, we analyze the direct and converse effect in laminate composites of magnetostrictive and piezoelectric materials. Our results deterministically show that direct magnetoelectric (ME) effect is maximized at ...
