Kemasukan fluks magnetik yang diaktifkan secara terma ke dalam gegelung pikap melalui empangan fluks di tinggi Tc peranti gangguan kuantum superkonduktor (SQUID) dikaji. Kelakuan pengaktifan haba ini dianalisis dari segi arus beredar yang mengalir dalam gegelung pikap. Ia ditunjukkan bahawa pengaktifan haba boleh dihalang apabila arus beredar menjadi jauh di bawah arus kritikal empangan fluks. Ia juga menunjukkan bahawa kita memerlukan masa menunggu yang lama untuk merealisasikan keadaan ini kerana arus yang beredar secara logaritma mereput dengan masa dalam kes pengaktifan haba. Hubungan antara pengaktifan haba dan arus beredar disahkan secara kualitatif dengan eksperimen. Kami juga menunjukkan kaedah untuk mengurangkan arus beredar secara paksa dan bukannya pengaktifan haba. Dalam kes ini, kita boleh menghalang pengaktifan haba tanpa menunggu masa yang lama.

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.
