据1985年8月20日“日本经济杂志”报道,东京大学的Yoichi Fujii利用双芯玻璃纤维干涉仪测得10~(-6)高斯的甚低磁场强度.其中一股芯采用磁致伸缩的镍片作传感器.用此仪器也可测得赫兹电流的磁场.
According to a report in Japan Economic Journal on August 20, 1985, Yoichi Fujii of the University of Tokyo reported a very low magnetic field strength of 10 -6 Gauss using a two-fiber glass fiber interferometer. One of the cores was magnetically Telescopic nickel as a sensor with this instrument can also measure the magnetic field Hertz current.
