A magneto-electric composite element of two functional materials: giant magnetostrictive (GMM) and piezoelectric materials, is developed for coil-less magnetic force control. This force control is based on the inverse magnetostrictive effect of GMM and realized by composing a closed parallel magnetic circuit with a permanent magnet in magnetic yoke. The magnetic force between two yokes can be adjusted by controlling the strain in the magnetostrictive rod. For the purpose of efficiently controlling the strain of the GMM rod, a magneto-electric composite element is constructed, in which the two functional materials: a giant magnetostrictive rod and a stack piezoelectric actuator, are mechanically coupled via strain. The magnetization in the GMM rod can be controlled by adjusting the voltage of the piezoelectric actuator. It is confirmed that this element works to adjust magnetic force and has wide frequency bandwidth. As an application of this element, a magnetic levitation system is proposed and the movable yoke was levitated by simple PD control. This system has advantages of low power consumptions and low heat generation compared with a conventional system with electromagnetic coils.

两种功能材料的磁电气复合元件：巨型磁刻录（GMM）和压电材料，用于无线圈磁力控制。该力控制基于GMM的反磁性效应，并通过在磁轭中用永久磁铁组成封闭的平行磁路来实现。可以通过控制磁梗杆中的应变来调整两个轭之间的磁力。为了有效地控制GMM杆的应变，构建了磁性复合元件，其中两种功能材料：巨磁杆和一个堆栈压电执行器是通过应变机械耦合的。可以通过调节压电执行器的电压来控制GMM棒中的磁化。证实该元素可以调节磁力并具有较大的频率带宽。作为该元素的应用，提出了磁性悬浮系统，并通过简单的PD控制悬浮了可移动的轭。与具有电磁线圈的常规系统相比，该系统具有低功率消耗和低热量的优势。
