单磁场驱动的Tb_1-xDy_xFe_2-y-Pb（Zr,Ti）O₃-Tb_1-xDy_xFe_2-y三层膜磁电效应

摘要: 研究了Tb_1-xDy_xFe_2-y(TDF)与锆钛酸铅(PZT)三层膜样品的制备和在单一直流磁场驱动下的磁电(ME)效应。在该系列三层膜样品中测量到了巨大的ME耦合效应,纵向场中,ME电压的最大变化范围可达1404V/cm。所得实验结果与同种样品的两磁场驱动的ME效应完全不同。这可能预示了某些新的物理内容。该技术可简化ME效应在某些实际应用中的复杂度。

Abstract: Tb_1-xDy_xFe_2-y-Pb（Zr,Ti）O₃-Tb_1-xDy_xFe_2-y trilayers have been fabricated.The ME effect induced by a single dc magnetic field in the layered materials has been investegated.A much enhanced ME voltage has been measured in the trilayers compared with that observed in bilayers Tb_1-xDy_xFe_2-y-Pb（Zr,Ti）O₃,the maximal variety of ME voltage is about 1404V/cm.The results obtained are far from that obtained from the two field-driven ME effect in the same material.This technique can be expected to simplify the applications of ME effect.
