Abstract

A DC superconducting quantum interference device (SQUID) using a new washer with an additional slit has been designed and fabricated in order to investigate the washer resonance of the SQUID coupled to a multiturn input coil. Current steps in I- Vcurves, which reflect the degree of washer resonance, are compared for the new and conventional washers. It is shown that the resonant step of the coupled SQUID is weakened much more with increasing length of the additional slit. This result agrees with simulation results, and confirms the usefulness of the new washer for the suppression of washer resonance.
