Inelastic electron tunneling spectroscopy of a Mn dimer
F. Delgado, J. Fernández-Rossier
A scanning tunneling microscope (STM) can probe the inelastic spin excitations of single magnetic atoms in a surface via spin-flip assisted tunneling. A particular and intriguing c…
Complete reversal of the atomic unquenched orbital moment by a single electron
R. Rejali, D. Coffey, J. Gobeil +3
The orbital angular moment of magnetic atoms adsorbed on surfaces is often quenched as a result of an anisotropic crystal field. Due to spin-orbit coupling, what remains of the orb…
Spin decoherence of magnetic atoms on surfaces
F. Delgado, J. Fernández-Rossier
We review the problem of spin decoherence of magnetic atoms deposited on a surface. Recent breakthroughs in scanning tunnelling microscopy (STM) make it possible to probe the spin…
The emergence of classical behavior in magnetic adatoms
F. Delgado, S. Loth, M. Zielinski +1
A wide class of nanomagnets shows striking quantum behavior, known as quantum spin tunneling (QST): instead of two degenerate ground states with opposite magnetizations, a bonding-…
Consequences of Kondo exchange on quantum spins
F. Delgado, C. F. Hirjibehedin, J. Fernandez-Rossier
When individual quantum spins are placed in close proximity to conducting substrates, the localized spin is coupled to the nearby itinerant conduction electrons via Kondo exchange.…
Intrinsic spin noise in MgO magnetic tunnel junctions
F. Delgado, K. Lopez, R. Ferreira +1
We consider two intrinsic sources of noise in ultra-sensitive magnetic field sensors based on MgO magnetic tunnel junctions, coming both from Mg nuclear spins (, 10%…
Probing a Single Nuclear Spin in a Silicon Single Electron Transistor
F. Delgado, R. Aguado, J. Fernández-Rossier
We study single electron transport across a single Bi dopant in a Silicon Nanotransistor to assess how the strong hyperfine coupling with the Bi nuclear spin affects the tr…
Storage of classical information in quantum spins
F. Delgado, J. Fernández-Rossier
Digital magnetic recording is based on the storage of a bit of information in the orientation of a magnetic system with two stable ground states. Here we address two fundamental pr…
