Excitation of local magnetic moments by tunnelling electrons
Jean-Pierre Gauyacq, Nicolas Lorente, Frederico Dutilh Novaes
The advent of milli-kelvin scanning tunneling microscopes (STM) with inbuilt magnetic fields has opened access to the study of magnetic phenomena with atomic resolution at surfaces…
Negative differential resistance in scanning tunneling microscopy: simulations on C-based molecular overlayers
Frederico D. Novaes, Manuel Cobian, Alberto Garcia +3
We determine the conditions in which negative differential resistance (NDR) appears in the C-based molecular device of [Phys. Rev. Lett. {\bf 100}, 036807 (2008)] by means o…
Quenching of magnetic excitations in single adsorbates at surfaces: Mn on CuN/Cu(100)
Frederico D. Novaes, Nicolás Lorente, Jean-Pierre Gauyacq
The lifetimes of spin excitations of Mn adsorbates on CuN/Cu(100) are computed from first-principles. The theory is based on a strong-coupling T-matrix approach that evaluates the…
Magnetic transitions induced by tunnelling electrons in individual adsorbed M-Phthalocyanine molecules (M Fe, Co)
Jean-Pierre Gauyacq, Frederico D. Novaes, Nicolás Lorente
We report on a theoretical study of magnetic transitions induced by tunnelling electrons in individual adsorbed M-Phthalocyanine (M-Pc) molecules where M is a metal atom: Fe-Pc on…
Oxygen clamps in gold nanowires
Frederico D. Novaes, Antonio J. R. da Silva, E. Z. da Silva +1
We investigate how the insertion of an oxygen atom in an atomically thin gold nanowire can affect its rupture. We find, using ab initio total energy density functional theory calcu…
