摘要: 研究了Tb1-xDyxFe2-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. 所得实验结果与同种样品在两磁场驱动下的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: In this paper we discuss the preparation of Tb1-xDyxFe2-y/Pb(Zr,Ti)O3 trilayers and a technique of single magnetic field-driven magnetoelectric coupling. A colossal ME voltage has been measured in the trilayers with the technique. The results obtained are far from that observed from that driven by two-field ME effect for the same material and probably predict some new physical effect. This technique can be expected to simplify the applications of ME effect in some fields.
