Hybrid superconducting quantum magnetometer

الأصل · EN

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/Phi₀ and intrinsic flux noise 10⁻⁹Phi₀ Hz⁻¹/² 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.
