Abstract: 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$/{\ensuremath{\Phi}}_{0}$ and intrinsic flux noise $\ensuremath{\sim}{10}^{\ensuremath{-}9}{\ensuremath{\Phi}}_{0}/\sqrt{\text{Hz}}$ below 1 K are achievable. The opportunity to access single-spin detection joined with limited dissipation (of the order of $\ensuremath{\sim}{10}^{\ensuremath{-}14}$ W) make this magnetometer interesting for the investigation of the switching dynamics of molecules or individual magnetic nanoparticles.
