针对以往高TC射频超导量子干涉器件(SQUID)磁强计中射频SQUID与衬底谐振器面对面放置的情况，设计并制作了一种简单的基于单片SrTiO_3双晶衬底谐振器的集成垫片式RF SQUID磁强计。该磁强计将射频SQUID、磁通聚焦和谐振器集成到一个芯片中。这种集成式垫圈类型的RF SQUID磁强计在将该设备集成到扫描SQUID检测系统中提供了卓越的优势，在该系统中，样品和SQUID之间的距离可以降至最小。
In contrast to the previous high-TC radio frequency (rf) superconducting quantum interference device (SQUID) magnetometer, in which the rf SQUID is placed face to face with the substrate resonator, a simple integrated washer-type rf SQUID magnetometer based on a single SrTiO3 bicrystal substrate resonator is designed and fabricated in this work. The magnetometer combines the rf SQUID, flux focusing, and resonator into a single chip. This integrated washer-type rf SQUID magnetometer offers a superior advantage in integrating the device to a scanning SQUID detection system in which the distance between the sample and SQUID can be minimized.
