    摘要： A high-sensitive magnetometer has two SQUIDs each comprising a superconducting loop with one or more Josephson junctions and also has a coil comprising a continuous loop for providing magnetic flux of input signals to each of the SQUIDs in opposite directions. The magnetic flux of the input signals is detected by sums of output voltages of the SQUIDs. Magnetic flux noises equally applied on the two SQUID are cancelled by the continuous loop and at addition of the output voltages of the SQUIDs, thus large output signals can be obtained because sums of the two SQUID output signals are obtained.

    摘要翻译： 高灵敏度磁力计具有两个SQUID，每个SQUID包括具有一个或多个约瑟夫逊结的超导回路，并且还具有包括连续回路的线圈，用于向相反方向的每个SQUID提供输入信号的磁通量。 通过SQUID的输出电压的和来检测输入信号的磁通量。 在两个SQUID上均等地施加的磁通量噪声被连续回路消除，并且加上SQUID的输出电压，因此可以获得大的输出信号，因为得到两个SQUID输出信号的和。
