A model for individual quantal nano-skyrmions
Jean-Pierre Gauyacq, Nicolas Lorente
A quantal model description of a discrete localized skyrmion singularity embedded in a ferromagnetic environment is proposed. It allows discussing the importance of various paramet…
Structural and magnetic properties of FeMn (1...6) chains supported on CuN / Cu (100)
Deung-Jang Choi, Roberto Robles, Jean-Pierre Gauyacq +3
Heterogeneous atomic magnetic chains are built by atom manipulation on a CuN/Cu (100) substrate. Their magnetic properties are studied and rationalized by a combined scanning t…
Electronic structure of atomic manganese chains supported on CuN / Cu (100)
Deung-Jang Choi, Roberto Robles, Jean-Pierre Gauyacq +3
Scanning tunnelling microscopy and density functional theory studies of manganese chains adsorbed on CuN/Cu (100) reveal an unsuspected electronic edge state at eV abo…
Entanglement-induced Kondo screening in atomic spin chains
Deung-Jang Choi, Roberto Robles, Shichao Yan +6
Quantum entanglement permeates the complex ground states of correlated electron materials defying single-particle descriptions. Coupled magnetic atoms have potential as model syste…
Spontaneous spin switching via substrate-induced decoherence
Jean-Pierre Gauyacq, Nicolás Lorente
We analyze the spontaneous switching between the two Néel states of Fe chains on CuN/Cu(100), experimentally studied by Loth et al. [Science 335, 196 (2012)]. We show that, in…
Correlation-mediated processes for electron-induced switching between Neel states of Fe anti-ferromagnetic chains
Jean-Pierre Gauyacq, Simeon Moises Yaro, Xavier Cartoixa +1
The controlled switching between two quasi-stable Neel states in adsorbed anti-ferromagnetic Fe chains has recently been achieved by Loth et al [Science 335, 196 (2012)]. In order…
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…
Many-body effects in magnetic inelastic electron tunneling spectroscopy
Richard Korytár, Nicolás Lorente, Jean-Pierre Gauyacq
Magnetic inelastic electron tunneling spectroscopy (IETS) shows sharp increases in conductance when a new conductance channel associated to a change in magnetic structure is open.…
Excitation of spin waves by tunnelling electrons in one-dimensional ferro and anti-ferromagnets
J. P. Gauyacq, N. Lorente
Excitation of finite chains of magnetic atoms adsorbed on a surface by tunnelling electrons from an STM (Scanning Tunnelling Microscope) tip is studied using a Heisenberg Hamiltoni…
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…
Efficient spin transitions in inelastic electron tunneling spec troscopy
Nicolás Lorente Jean-Pierre Gauyacq
The excitation of the spin degrees of freedom of an adsorbed atom by tunneling electrons is computed using a strong coupling theory. The excitation process is shown to be a sudden…
Optimization of a Langmuir-Taylor detector for lithium
R. Delhuille, A. Miffre, E. Lavallette +6
This paper describes the construction and optimization of a Langmuir-Taylor detector for lithium, using a rhenium ribbon. The absolute detection probability of this very sensitive…
