研究了FeGa/BaTiO3/FeGa ME层状复合材料的电阻载荷效应。结果表明:(1)ME电压系数随阻性负载的增加而增大并趋于饱和;(2)随着阻性负载的增加,ME的截止频率和谐振频率均向低频侧移动并趋于开路状态下的值;(3)ME的输出功率可以通过改变附加的阻性负载来调节,以达到最佳的有功状态。本研究为ME传感器及其电子电路的设计提供了依据。
The electrical resistance load effects on an ME laminated composite of FeGa/BaTiO3/FeGa are investigated. The results show that (i) The ME voltage coefficient increases and tends to be saturated with the increase in electrical resistance load, (ii) the cutoff frequency and the resonance frequency both shift to the lower frequency side and approach to the values under open-circuit condition with the increase in electrical resistance load, and (iii) the ME output power can be adjustable by changing the attached electrical resistance load to achieve the best active status. The present study provides the basis for the design of ME sensors and their electronic circuits.
