摘　　要：ＤＣ－ＳＱＵＩＤｓ由铊膜制备．用两种方法测量了闭环ＤＣ－ＳＱＵＩＤ磁强计的噪声．研究了环境噪声对磁强计噪声测量的影响．Abstract DC-SQUIDs were prepared by TlBaCaCuO thin films. The noise properties of these devices have been determined by operating them in the flux lockedloop usins two kinds of method. The influence of environments noise for magnetometer have also been studied.
