Transmission of correlated electrons through sharp domain walls in magnetic nanowires: a renormalization group approach
M. A. N. Araujo, V. K. Dugaev, V. R. Vieira +2
The transmission of correlated electrons through a domain wall in a ferromagnetic one dimensional system is studied theoretically in the limit of a domain wall width smaller or com…
Role of electron correlations in transport through domain walls in magnetic nanowires
M. A. N. Araujo, V. K. Dugaev, V. R. Vieira +2
The transmission of correlated electrons through a domain wall in ferromagnetic quasi-one-dimensional systems is studied theoretically in the case when the domain wall width is com…
Electron transmission between normal and heavy electron metallic phases in a Kondo lattice system
M. A. N. Araujo, A. H. Castro Neto
The interface between a heavy electron coherent metallic phase and an incoherent normal metal phase is discussed. The Fermi momentum mismatch between the two phases causes the carr…
Weak ferromagnetism and spiral spin structures in honeycomb Hubbard planes
M A N Araujo, N M R Peres
Within the Hartree Fock- RPA analysis, we derive the spin wave spectrum for the weak ferromagnetic phase of the Hubbard model on the honeycomb lattice. Assuming a uniform magnetiza…
Comment on "Gapless Spin-1 Neutral Collective Mode Branch for Graphite"
N. M. R. Peres, M. A. N. Araujo, A. H. Castro Neto
Comment on "Gapless Spin-1 Neutral Collective Mode Branch for Graphite" by G. Baskaran and S.A. Jafari [cond-mat/0110022; Physical Review Letters, 89, 016402 (2002)].
Magnetic and superconducting instabilities in the periodic Anderson model: an RPA stud
N. M. R. Peres, M. A. N. Araujo
We study the magnetic and superconducting instabilities of the periodic Anderson model with infinite Coulomb repulsion U in the random phase approximation. The Neel temperature and…
