열적으로 활성화된 자속이 높은 플럭스 댐을 통해 픽업 코일로 유입됨 Tc 초전도 양자간섭소자(SQUID)를 연구합니다. 이러한 열 활성화의 거동은 픽업 코일에 흐르는 순환 전류의 관점에서 분석됩니다. 순환 전류가 플럭스 댐의 임계 전류보다 훨씬 낮아질 때 열 활성화가 방지될 수 있음을 보여줍니다. 또한 열 활성화의 경우 순환 전류가 시간에 따라 대수적으로 감소하기 때문에 이러한 상황을 실현하려면 긴 대기 시간이 필요함을 보여줍니다. 열 활성화와 순환 전류 사이의 관계는 실험을 통해 정성적으로 확인되었습니다. 또한 열 활성화 대신 순환 전류를 강제로 줄이는 방법도 보여줍니다. 이 경우 긴 대기 시간 없이 열 활성화를 방지할 수 있습니다.

Abstract: Thermally activated magnetic-flux entry into a pickup coil through a flux dam in high Tc superconducting quantum interference device (SQUID) is studied. The behavior of this thermal activation is analyzed in terms of the circulating current flowing in the pickup coil. It is shown that the thermal activation can be prevented when the circulating current becomes much below a critical current of the flux dam. It is also shown that we need a long waiting time in order to realize this situation since the circulating current logarithmically decays with time in the case of the thermal activation. The relationship between the thermal activation and the circulating current is qualitatively confirmed with the experiment. We also show a method in order to forcibly reduce the circulating current instead of the thermal activation. In this case, we can prevent the thermal activation without the long waiting time.

AB - Thermally activated magnetic-flux entry into a pickup coil through a flux dam in high Tc superconducting quantum interference device (SQUID) is studied. The behavior of this thermal activation is analyzed in terms of the circulating current flowing in the pickup coil. It is shown that the thermal activation can be prevented when the circulating current becomes much below a critical current of the flux dam. It is also shown that we need a long waiting time in order to realize this situation since the circulating current logarithmically decays with time in the case of the thermal activation. The relationship between the thermal activation and the circulating current is qualitatively confirmed with the experiment.
