1. Giant magnetostrictive Fe-Ga alloys are expected as actuator/sensor materials with high respective velocity and huge stress created by the magnetostriction. In order to develop magnetostrictive material induced by low magnetic field, we investigated magnetostrictive (positive magnetostriction / negative magnetostriction) bimorph-layers, that is, Fe_<80>Ga_<20> ribbon (146 μm)/ Ni (14 μm) film by magnetron sputtering system. The Fe_<80>Ga_<20> ribbon was prepared by rapidly solidification. Magnetostrictive property of the cantilever-type foil was measured using an optical lever method. Displacement of the upper part of the foil with length of 22 mm was 530 pin under low steady magnetic field of 40 kAm^<-1> and exhibits.- little hysteresis. These magnetostrictive properties also are maintained under low frequency of alternating magnetic field. Moreover, the displacement of the foil at the mechanical resonance frequency exhibits a peak and reaches to 2.0 mm at week magnetic field of 50 Oe.2. The, magnetostrictive bimorph-layers was applied to micro-gas valve. These cantilever-type actuators can be bent by applying magnetic field parallel to length. A point of the actuator displaced about 300 μm under 500 Oe. The opening and closing action of a gas-valve consisted of magnetostrictive actuator can be controlled remotely by magnetic fields. Flow rate of gas can be driven 50 to 0 cc min^<-1> upon increasing magnetic field to 3500e. Response time after applying of magnetic field is below 0.15 sec, it is fast:

1。巨型磁梗死的Fe-GA合金被预期为执行器/传感器材料，具有较高的相对速度和巨大的压力是磁曲折产生的。为了开发低磁场诱导的磁静脉材料，我们研究了磁体阻滞性（阳性磁静脉 /负磁脑）双层层，即Magnetron Sputtering System通过Magnetron Sputtering系统。 Fe_ <80> Ga__ <20>丝带是通过快速固化制备的。使用光杠杆方法测量悬臂式铝箔的磁刻；在40 kam^<-1>的低稳态磁场下，箔的上部的位移为22 mm，为530引脚，展览。这些磁性特性还保持在替代磁场的低频下。此外，机械共振频率下的箔的位移表现出峰值，在50 OE.2的周磁场时达到2.0 mm。将磁性双层层应用于微气体阀。这些悬臂型致动器可以通过平行于长度施加磁场来弯曲。执行器的点在500 OE以下约300μm。由磁执行器组成的气体阀的开口和闭合作用可以由磁场远程控制。在将磁场增加到3500E时，气体的流速可以驱动50至0 cc min^<-1>。应用磁场后的响应时间低于0.15秒，它很快：
