压电：磁致伸缩复合材料中的磁电耦合（α（E））是通过其界面处的机械应变来介导的。将磁性纳米颗粒（NPs）分散在压电基体中增加了两相之间的界面面积，因此可以预期大的α（E）。在这里，我们提出了3-0型纳米复合薄膜的电和ME性能的各种浓度的CoFe 2 O 4纳米颗粒分散在PbZr0.52Ti0.48O3（PZT）矩阵。纳米复合薄膜显示只有轻微的减少，在剩余的电极化相比，PZT。具有0.1%CoFe2O4（摩尔浓度）的纳米复合膜在453 Oe直流偏压和1 kHz下表现出最高的横向α（E）为549 mV/cmOe。(C)2013年美国物理学会。[http：//dx.doi.org/10.1063/1.4799174]
Magnetoelectric (ME) coupling (alpha(E)) in piezoelectric: magnetostrictive composites is mediated through mechanical strain at their interfaces. Incorporating magnetic nanoparticles (NPs) in piezoelectric matrix enhances interfacial area between the two phases and therefore large alpha(E) can be expected. Here, we present electric and ME properties of 3-0 type nanocomposite thin films with various concentrations of CoFe2O4 NPs dispersed in PbZr0.52Ti0.48O3 (PZT) matrix. Nanocomposite films show only a slight reduction in remnant electric-polarization as compared to that of PZT. A nanocomposite film with 0.1% CoFe2O4 (molar concentration) exhibited the highest transverse alpha(E) of 549 mV/cmOe at 453 Oe dc bias and 1 kHz. (C) 2013 American Institute of Physics.
