超磁致伸缩材料是一种新型的磁?机械转换材料，具有磁致伸缩系数大，能量密度高，机电耦合系数大，响应速度快等优点。
In our experimentation , we combine fiber bragg grating with tb - dy - fe single crystal , we can measure the current which produces the magnetic field when we measure the shift of bragg wavelength because of magnetostrictive strain of tb - dy - fe single crystal in magnetic field , we also study the relation between bias field , strain of current sensor
本实验将光纤布拉格光栅与tb - dy - fe结合起来，利用tb - dy - fe在磁场下的伸缩引起布拉格波长的改变，来测量产生磁场的待测电流的大小。在实验中我们还研究了偏场，预应力与传感器的关系，在这个过程中我们找到了与传感器有关的最佳设计参数。
