The resonant magnetoelectric (ME) effect of FeSiB/Pb(Zr,Ti)O (FeSiB/PZT) composites with a surface-modified FeSiB amorphous alloy has been studied. The surface-modified FeSiB can improve the ME coefficient at the resonant frequency by optimizing the magnetomechancial power conversion efficiency. The maximum ME coefficient of the surface-modified ribbons combined with soft PZT (PZT5) is two-thirds larger than that of the composites with fully amorphous ribbons. Meanwhile, the maximum value of the ME coefficient with surface-modified FeSiB ribbons and hard PZT (PZT8) is one-third higher compared with the fully amorphous composites. In addition, experimental results of magnetomechanical coupling properties of FeSiB/PZT composites with or without piezoelectric layers indicate that the power efficiency of the composites first decreases and then increases with the increase in the number of FeSiB layers. When the surface crystalline FeSiB ribbons are combined with a commercially available hard piezoelectric ceramic plate, the maximum magnetoelectric coupling coefficient of the ME composite reaches 5522 V/(Oe*cm), of which the electromechanical resonant frequency is 23.89 kHz.
研究了具有表面改性FeSiB非晶合金的FeSiB/Pb(Zr,Ti)O(FeSiB/PZT)复合材料的共振磁电(ME)效应。表面改性的FeSiB可通过优化磁机械功率转换效率来提高共振频率下的ME系数。与完全非晶带材的复合材料相比,表面改性带材与软PZT(PZT5)结合的最大ME系数大2/3。同时,表面改性FeSiB带材与硬PZT(PZT8)结合的ME系数最大值比完全非晶复合材料高1/3。此外,有或无压电层的FeSiB/PZT复合材料的磁机械耦合性能实验结果表明,复合材料的功率效率随FeSiB层数的增加先降低后增加。当表面结晶的FeSiB带材与市售硬压电陶瓷板结合时,ME复合材料的最大磁电耦合系数达到5522 V/(Oe*cm),其中机电共振频率为23.89 kHz。
