Paper Abstract

The influence of small external magnetic field on microwave properties of superconductor thick film ring resonators has been studied at various cryogenic temperatures. The ring resonators made of (formula available in paper) materials were realized by screen printing on yttrium stabilized ZrO2(YSZ) and (100) oriented single crystal MgO substrates. External magnetic fields were found to have a strong effect on the microwave reflection of the superconducting ring resonators. These magnetic field-controllable microwave resonators may offer (1) a new method to improve the properties of microwave resonators and other microwave devices and (2) a new method to construct new types of devices (e.g., magnetic field sensors of high sensitivity).
