Abstract Lorentz force-piezoelectric coupled magnetoelectric (ME) effect and piezomagnetic-piezoelectric coupled ME effect were compared in PZT/nonmagnetic and PZT/magnetostrictive metal cylindrical layered composites under axial magnetic fields. While only the Lorentz force-piezoelectric ME effect is observed in PZT/brass and PZT/Al cylinders, both ME effects are present in PZT/magnetostrictive Ni cylinder. The ME voltage linear dependence on DC magnetic field and constant −90° ME voltage phase reflect the Lorentz force-piezoelectric ME effect. For the PZT/Ni cylinder under low DC magnetic field, the ME voltages from the two ME effects tend to be anti-phase, and the piezomagnetic-piezoelectric ME voltage is much higher than the Lorentz force-piezoelectric ME voltage. However, under high DC magnetic field, the Lorentz force-piezoelectric ME effect plays a dominant role. These results indicate that the PZT/Ni cylinder is favorable to DC magnetic field detection in wide range.

具有 PZT/磁致伸缩和非磁性金属层的圆柱形复合材料中的洛伦兹力感应磁电效应

摘要 在轴向磁场作用下，比较了PZT/非磁性和PZT/磁致伸缩金属圆柱层状复合材料的洛伦兹力-压电耦合磁电（ME）效应和压电-压电耦合ME效应。虽然在 PZT/黄铜和 PZT/Al 圆柱体中仅观察到洛伦兹力 - 压电 ME 效应，但在 PZT/磁致伸缩 Ni 圆柱体中存在两种 ME 效应。ME 电压对 DC 磁场的线性依赖性和恒定的 -90° ME 电压相位反映了洛伦兹力 - 压电 ME 效应。对于低直流磁场下的 PZT/Ni 圆柱体，两种 ME 效应产生的 ME 电压趋于反相，压电-压电 ME 电压远高于洛伦兹力-压电 ME 电压。然而，在高直流磁场下，洛伦兹力压电 ME 效应起主导作用。这些结果表明，PZT/Ni 圆柱体有利于大范围的直流磁场检测。
