文摘

We present the first measurements on the proposed magnetically-tuned superconducting transition-edge sensor and compare the modified resistive transition with the theoretical prediction (Sadleir et al., IEEE Trans App Supercond 23:2101405, 2013). A TES’s resistive transition is customarily characterized in terms of the unitless device parameters \(\alpha \) and \(\beta \) corresponding to the resistive response to changes in temperature and current respectively. We present a new relationship between measured IV quantities (sensor current \(I\) and voltage \(V\) ) and the parameters \(\alpha \) and \(\beta \) and use these relations to confirm we have stably biased a TES with negative \(\beta \) parameter with magnetic tuning. Motivated by access to this new unexplored parameter space, we investigate the conditions for bias stability of a TES taking into account both self and externally applied magnetic fields.
