通过化学沉积法制备了磁电（ME）Ni-PZT-Ni圆柱形层状复合材料。 ME效应是通过施加平行于和垂直于圆柱轴方向的恒定磁场和交变磁场来测量的。 ME 电压系数随气缸直径的增加而增加。实验和计算数据均表明，Ni-PZT-Ni 圆柱形层状复合材料的共振频率随着圆柱直径的增加而降低。我们可以利用共振频率的这一特性来设计一种具有可控共振ME耦合的ME复合材料。
Magnetoelectric (ME) Ni–PZT–Ni cylindrical layered composites have been prepared by electroless deposition. The ME effect was measured by applying both constant and alternating magnetic fields parallel and perpendicular to the cylinder axis direction. The ME voltage coefficient increases with cylinder diameter. Both experimental and calculated data indicate that the resonance frequency of Ni–PZT–Ni cylindrical layered composites decreases with increasing cylinder diameter. We can apply this characteristic of resonance frequency to design a kind of ME composites with the controllable resonance ME coupling.
