Characterization of YBCO/Au/YBCO resistors for HTS Josephson noise thermometry

It has been proposed that an absolute thermometer based on the linewidth broadening of the Josephson oscillation could be realized in the temperature range 10 K to 50 K with the use of high-temperature-superconducting resistive superconducting quantum interference devices (HTS R-SQUIDs). Although th...

Zusammenfassung:It has been proposed that an absolute thermometer based on the linewidth broadening of the Josephson oscillation could be realized in the temperature range 10 K to 50 K with the use of high-temperature-superconducting resistive superconducting quantum interference devices (HTS R-SQUIDs). Although this technique has been successfully demonstrated with LTS devices in the temperature region below 1 K, there are unresolved problems which have so far prevented its translation to higher operating temperatures. A crucial component of a resistive SQUID noise thermometer is the shunt resistor, which is required to have a value
