Intermediate states of superconducting thermometers for x-ray microcalorimeters

Intermediate states near normal-superconducting transition at ~100mK, important for a sensitive thermometer in x-ray calorimetry, have been studied by an imaging technique based on Low Temperature Scanning Synchrotron Microscopy (LTSSM). In conjunction with iridium superconducting transition-edge sensors operating in electrothermal feedback mode, the LTSSM visualizations reveal that a normal-superconducting phase separation takes place in the actual intermediate states.

Fluxon pinning through interaction with the superconducting wiring of long annular Josephson junctions

The statics and dynamics of magnetic flux quanta (fluxons) in long annular Josephson tunnel junctions have been investigated. Pinning by interaction of the fluxon field outside the junction with the superconducting wiring has been observed in spatially resolving measurements using low-temperature scanning electron microscopy. We were able to influence the characteristics of this field by carefully modifying the beam-induced fluxon trapping procedure. In this way we were able to select the pinning site acting on the fluxon.
