    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 Al2O3islands on a NiAl surface. We find pronounced variations of the spin-flip spectra for manganese atoms in different local environments.
