Abstract

An RF-SQUID (superconducting quantum interference device) gradiometer integrated in a lambda /2 length microstrip resonator is described. The device was realized with low-temperature superconductors (LTS) using a shunted NbN/MgO/NbN SIS (superconductor-insulator-superconductor) junction as the active element. Various measurement results are given. Measurements of the complex reflection coefficient clearly show a periodic dependence on an applied DC flux. Due to the fully planar design, the SQUID is an appropriate basic element of a one-chip magnetometer including flux transformer. Work is under way to realize the circuit in high-temperature superconductors.<>

用于高温超导应用的平面x波段squid梯度计设计

介绍了一种集成在λ /2长度微带谐振腔中的RF-SQUID(超导量子干涉器件)梯度计。该器件采用NbN/MgO/NbN SIS(超导体-绝缘体-超导体)分路结作为有源元件实现低温超导体(LTS)。给出了各种测量结果。复反射系数的测量清楚地显示出对施加的直流磁通的周期性依赖。由于全平面设计，SQUID是包含磁通变压器的单片磁强计的合适基本元件。在高温超导体中实现这种电路的工作正在进行中。
