Fig. 2: Readout of different nuclear spin states.
From: Single-shot readout of the nuclear spin of an on-surface atom
a Energy diagram of the spin states as a function of magnetic field (top) and schematic of the experiment shown in (b), indicating that at certain tip heights fprobe matches the Zeeman splitting corresponding to one of ml states (bottom). b Color map of current histograms similar to Fig. 1d for different heights of the magnetic STM tip (bias voltage 60 mV). The horizontal axis represents the mean current for each time trace, which is a measure of the total magnetic field. c–f Current histograms, corresponding to the labeled vertical dashed lines in (b).
