  Superconductor-ferromagnet thermoelectric detector (SFTED) is a novel
ultrasensitive radiation detector based on the giant thermoelectric effect in
superconductor-ferromagnet tunnel junctions. This type of detector can be
operated without the need of additional bias lines, and is predicted to provide
a performance rivaling transition-edge sensors and kinetic inductance
detectors. Here we report our numerical studies on the SFTED noise equivalent
power, energy resolution and time constant, and the feasibility of a SQUID
readout in both bolometric and calorimetric regimes, with the goal to provide
practical design parameters for the detector fabrication and the readout
circuitry implementation.
