使用简单的补偿方法，我们开发了移动式高温超导射频 SQUID 磁力计。直流和低频（20 Hz 以下）磁场可以得到很好的补偿。通过补偿，HTS RF SQUID 磁力计在地球磁场中大角度摆动时保持锁定。对于大于 20 Hz 的频率，在地球场中移动 SQUID 系统后，未观察到通量噪声增加。使用移动式 HTS RF SQUID 磁力计，我们构建了涡流 NDE 系统，该系统证明了检测铁磁材料缺陷的可能性。
Using a simple compensation method, we developed a mobile HTS RF SQUID magnetometer. The dc and low frequency (below 20 Hz) magnetic field could be compensated very well. With the compensation, the HTS RF SQUID magnetometer remained locked while being swung at large angles in the Earth's field. For frequencies greater than 20 Hz, there was no increase in the flux noise observed after moving the SQUID system in the Earth's field. Using the mobile HTS RF SQUID magnetometer, we constructed an eddy current NDE system, which demonstrated the possibility of detecting defects in ferromagnetic materials.
