Superparamagnetic tip. a, b Magnetic-field-dependent dI/dV plots in a and b extracted from the hysteresis loops of Fig. 2c, d respectively. The dI/dV curves at each temperature are normalized by fits using Eq. 8, as shown by the solid curves. The legend gives the measurement temperature and the total magnetic moment in μB, as extracted from the fit of the data with the Eq. 8. c, Plots of all dI/dV values as a function of reduced magnetic field (μ0 H/T). The inset is a close-up of the plots around μ0(HH off)/T = 0. The gray curve shows the Langevin fit in one curve for all data
