Resumen: | We propose a universal mechanism that makes it possible to drive an individual atomic spin using a spin-polarized scanning tunnel microscope (STM) with an oscillating electric signal. We show that the combination of the distance-dependent exchange with the magnetic tip and the electrically driven mechanical oscillation of the surface spins permits us to control their quantum state. Based on a combination of density functional theory and multiplet calculations, we show that the proposed mechanism is essential to account for the recently observed electrically driven paramagnetic spin resonance (ESR) of an individual Fe atom on a MgO/Ag(100) surface. Our findings set the foundation to deploy the ESR-STM quantum sensing technique to a much broader class of systems. |
