在这封信中，我们介绍了使用与基于高温超导体（HTS）的超导量子干涉装置（SQUID）耦合的未调谐拾波线圈检测核磁共振（NMR）信号的实验结果。我们能够在高达 500 高斯的静态场和高达 6 高斯的射频场的情况下操作 HTS SQUID。 HTS SQUID 检测 NMR 信号的能力为使用灵敏检测器进行涉及需要宽检测带宽的 NMR 的实际应用提供了可能性。
In this letter, we present results of experiments in which nuclear magnetic resonance (NMR) signals were detected using an untuned pickup coil coupled to a high temperature superconductor (HTS) based superconducting quantum interference device (SQUID). We were able to operate the HTS SQUID in the presence of static fields of up to 500 Gauss and radio frequency fields of up to 6 Gauss. The ability of a HTS SQUID to detect NMR signals opens up the possibility of using a sensitive detector for practical applications involving NMR that require a broad detection bandwidth.
