在高磁导率磁致伸缩 FeBSiC 合金带与压电 Pb(Zn-1/3,Nb-2/3)O-3-7%PbTiO3 单晶纤维层压而成的长型复合材料中发现了巨磁电 (ME) 电压和电荷系数。在 2 Oe 的极低直流磁偏压下，低频下的最大 ME 电压和电荷系数分别为 10.5 V/cm Oe 和 1 nC/Oe；在共振时，这些系数分别急剧增加至 400 V/cm Oe 和 42 nC/Oe。与之前报道的基于 Terfenol-D 的 ME 层压板相比，这些值要高得多，所需的直流磁偏压要低得多。 (C) 2007 年美国物理研究所。
Giant magnetoelectric (ME) voltage and charge coefficients have been found in long-type composites of high-permeability magnetostrictive FeBSiC alloy ribbons laminated together with piezoelectric Pb(Zn-1/3,Nb-2/3)O-3-7%PbTiO3 single crystal fibers. The maximum ME voltage and charge coefficients at low frequencies were 10.5 V/cm Oe and 1 nC/Oe under a notably low dc magnetic bias of 2 Oe; at resonance, these coefficients were dramatically increased to 400 V/cm Oe and 42 nC/Oe, respectively. These values are much higher, and the required dc magnetic bias much lower, than those of previously reported Terfenol-D based ME laminates. (C) 2007 American Institute of Physics.
