Magnetic hysteresis of dI/dV in spin-polarized STM/S. a STM image of two triangular Co cores of Fe-decorated Co islands on which the magnetic-field-dependent dI/dV were measured. The inset shows the apparent STM height profile along the white solid line. (V b = −0.2 V; I set = 1 nA). b A schematic of spin-STM measurement on a bilayer Co island in an external magnetic field μ0 H. c A set of dI/dV curves measured under a varying μ0 H ext at the position “1” marked in a. (V stab = 0.5 V; I stab = 1 nA). d Magnetic hysteresis extracted from the field dependence of dI/dV values at V b = −0.85 V (c)
