给出了在交流电驱动电压激励下，压电纤维/Metglas双层复合材料在直流偏压和直流磁场偏置作用下的实验数据。正如以前的研究报道的那样，存在直流偏置以最大化反向磁电系数。实验数据表明，最佳直流偏置是外加直流电压的函数。此外，还发现存在一个最佳的直流偏压，以进一步最大化逆磁电系数。
Experimental data on a piezofiber/Metglas bilayer composite subjected to both a dc electric voltage bias and a dc magnetic field bias while exciting it with an ac electric driving voltage are presented. As reported in previous studies, a dc magnetic field bias exists to maximize the converse magnetoelectric coefficient. Experimental data show that the optimum dc magnetic field bias is a function of applied dc electric voltage. Furthermore, it is revealed that an optimum dc electric voltage bias exists to further maximize the converse magnetoelectric coefficient.
