Hybrid superconducting quantum magnetometer

F. Giazotto, F. Taddei

A superconducting quantum magnetometer based on magnetic flux-driven modulation of the density of states of a proximized metallic nanowire is theoretically analyzed.With optimized geometrical and material parameters transfer functions up to a few mV/0 and intrinsic flux noise ∼10−9Φ0/√Hz below 1 K are achievable. The opportunity to access single-spin detection joined with limited dissipation (of the order of ∼10−14 W) make this magnetometer interesting for the investigation of the switching dynamics of molecules or individual magnetic
nanoparticles.
