Numerical simulations: (a,b) Current (in units of eΓs) and differential conductance maps with Fermi level and magnetic field, respectively. The magnetic field is in units of the Stoner-Wohlfarth switching field of the N-electron particle. The Fermi level is in units of the anisotropy energy per spin. (c) The conductance map in wider magnetic field range, showing crossover to the linear regime in strong magnetic field. (d) Map of the particle time averaged spin-z component, showing magnetic inversion at low Fermi level and below the switching field. (e) Conductance traces at three different fields obtained from (b), offset for clarity. (f) Map of the variance of the spin z-component, showing enhancement of magnetic noise in the regime of inverted relaxation.
