在这篇文章中，我们在Tb0.3Dy0.7Fe2（Terfenol-D）和Pb(Zr,Ti)O3的双层磁电复合材料中发现了共振频率下磁场诱导的巨相移效应。当偏置磁场从0.1 T变化到0.3 T时，83.2 kHz下磁电效应的相移高达180°，这意味着从电容行为到电感行为的完全转变。在极坐标下对相移进行了分析，认为这种巨大的相移机理是Terfenol-D的ΔE效应。这种巨大的相移效应可能有利于现有的相位调制技术。
In this letter we present a magnetic field-induced giant phase shift effect under resonant frequency in the bilayered magnetoelectric composite of Tb0.3Dy0.7Fe2(Terfenol-D) and Pb(Zr,Ti)O3. When the bias magnetic field is varied from 0.1 T to 0.3 T, the phase shift of the magnetoelectric effect under 83.2 kHz was as large as 180°, which implies a complete transformation from capacitor behavior to inductor behavior. The phase shift was analyzed in the polar coordinates, and the mechanism of this giant phase shift was considered as the ΔE effect of Terfenol-D. This giant phase shift effect may benefit existing phase modulation techniques.
