Localized magnetic states in graphene.
We examine the conditions necessary for the presence of localized magnetic moments on adatoms with inner shell electrons in graphene. We show that the low density of states at the Dirac point, and the anomalous broadening of the adatom electronic level, lead to the formation of magnetic moments for arbitrarily small local charging energy. As a result, we obtain an anomalous scaling of the bound...
متن کاملLocalized magnetic states in biased bilayer and trilayer graphene.
We study the localized magnetic states of an impurity in biased bilayer and trilayer graphene. It is found that the magnetic boundary for bilayer and trilayer graphene shows mixed features of Dirac and conventional fermions. For zero gate bias, as the impurity energy approaches the Dirac point, the impurity magnetization region diminishes for bilayer and trilayer graphene. When a gate bias is a...
متن کاملTransport through superconductor/magnetic dot/superconductor structures
The coupling of two s-wave superconductors through a small magnetic dot is discussed. Assuming that the dot charging energy is small compared to the superconducting gap, Ec D, and that the moment of the dot is classical, we develop a simple theory of transport through the dot. The presence of the magnetic dot will position Andreev bound states within the superconducting gap at energies tunable ...
متن کاملAndreev Bound States in Ferromagnet - Superconductor Nanostructures ⋆
We discuss the properties of a ferromagnet superconductor heterostructure on the basis of a Hubbard model featuring exchange splitting in the ferromagnet and electron electron attraction in the superconductor. We have solved the spin polarized Hartree Fock Gorkov equations together with the Maxwell’s equation (Ampere’s law) fully self-consistently. We have found that a Proximity Effect Fulde Fe...
