我们报道了一种超低噪声薄膜超导量子干涉装置（SQUID）磁强计的研制。铌薄膜拾取线圈连接到SQUID电流传感器的输入线圈上。所使用的亚微米交叉型约瑟夫森结的低电容使器件具有优越的噪声性能。讨论了该技术在地球物理和超低场磁共振成像等领域的应用。
We report on the development of an ultralow-noise thin-film-based superconducting quantum interference device (SQUID) magnetometer. A niobium thin-film pickup coil is connected to the input coil of a SQUID current sensor. The low capacitance of the used submicrometer cross-type Josephson junctions enables superior noise performance of the device. Application scenarios, e.g., in geophysics and ultralow-field magnetic resonance imaging, are discussed.
