Recently bulk tb - dy - fe single crystals have been obtained by magnetic levitation cold crucible without contamination in wuhan university of technology. these excellent single crystals, possessing a large displacement output under low magnetic field, build a foundation for the fabrication of the high precision micro - displacement actuators. the purpose of this research is to manufacture an advanced micro - displacement actuator with this high performance single crystal as the driving unit
常規的磁致伸縮型微位移致動器大多採用多晶或具有孿晶結構的磁致伸縮材料作為驅動單元，由於晶界和孿晶界對疇壁的移動具有阻礙作用，其低場下的位移輸出較小，調控精度受到很大影響。
