Fabio Donati’s research focuses on the magnetism and quantum coherence of surface-supported individual atoms and molecules. His main achievement is the discovery of magnetic stability in single rare earth atoms, a result that proves the possibility of downscaling magnetic memories down to the ultimate limit of an atom. His experimental expertise includes X-ray Magnetic Circular Dichroism (XMCD), Scanning Tunneling Microscopy (STM) and Electron Spin Resonance (ESR).
