Transition-Edge-Sensor utilizing the Magnetic Superconducting Transition

We present experimental results from a Transition-Edge-Sensor (TES) based on the magnetic superconducting transition. For the devices reported here, the change in magnetic flux from a microscale disk of electrodeposited tin may be detected by a planar pickup coil consisting of a niobium thin film. We present experimental data revealing the magnetic superconducting transition that is the basis for the principle of transduction between temperature and magnetic flux. The prototype magnetic TES devices may ultimately be utilized for microscale magnetometry or microcalorimetry. We present experimental data without and with a source of ionizing radiation as an experimental demonstration applicable to microcalorimetry.
