Magnetocrystalline anisotropy energy of Fe, Fe slabs and nanoclusters: a detailed local analysis within a tight-binding model
Dongzhe Li, Alexander Smogunov, Cyrille Barreteau +2
We report tight-binding (TB) calculations of magnetocrystalline anisotropy energy (MAE) of Iron slabs and nanoclusters with a particuler focus on local analysis. After clarifying v…
Electronic transport in iron atomic contacts: from the infinite wire to realistic geometries
Gabriel Autes, Cyrille Barreteau, Daniel Spanjaard +1
We present a theoretical study of spin polarized transport in Fe atomic contacts using a self-consistent tight-binding Hamiltonian in a non-orthogonal , and basis set, t…
Orbital contribution to the magnetic properties of iron as a function of dimensionality
Marie-Catherine Desjonquères, Cyrille Barreteau, Gabriel Autes +1
The orbital contribution to the magnetic properties of Fe in systems of decreasing dimensionality (bulk, surfaces, wire and free clusters) is investigated using a tight-binding ham…
Orbital contribution to the magnetic properties of nanowires: Is the orbital polarization ansatz justified?
Marie-Catherine Desjonqueres, Cyrille Barreteau, Gabriel Autes +1
We show that considerable orbital magnetic moments and magneto-crystalline anisotropy energies are obtained for a Fe monatomic wire described in a tight-binding method with intra-a…
Magnetism of iron: from the bulk to the monoatomic wire
Gabriel Autes, Cyrille Barreteau, Daniel Spanjaard +1
The magnetic properties of iron (spin and orbital magnetic moments, magnetocrystalline anisotropy energy) in various geometries and dimensionalities are investigated by using a par…
Diffusion rates of Cu adatoms on Cu(111) in the presence of an adisland nucleated at FCC or HCP sites
Mihai-Cosmin Marinica, Cyrille Barreteau, Daniel Spanjaard +1
The surface diffusion of Cu adatoms in the presence of an adisland at FCC or HCP sites on Cu(111) is studied using the EAM potential derived by Mishin {\it et al.} [Phys. Rev. B {\…
