Single-Atom Spin-Flip Spectroscopy

A. J. Heinrich,* J. A. Gupta, C. P. Lutz, D. M. Eigler

We demonstrate the ability to measure the energy required to flip the spin of single adsorbed atoms. A low-temperature, high–magnetic field scanning tunneling microscope was used to measure the spin excitation spectra of individual manganese atoms adsorbed on Al2O3 islands on a NiAl surface. We find pronounced variations of the spin-flip spectra for manganese atoms in different local environments.
