Nuclear magnetic relaxation for the spin-degenerate Anderson model
(Elsevier B.V., 1991-05-01)
A renormalization-group calculation of the temperature-dependent nuclear spin relaxation rate for a magnetic impurity in a metallic host is reported. The calculation follows a simplified procedure, which produces accurate ...
Collapse of the G d 3 + ESR fine structure throughout the coherent temperature of the Gd-doped Kondo Semiconductor CeF e 4 P 12
(American Physical Society, 2016-12-15)
Recent experiments on Gd3+ electron-spin resonance (ESR) in the filled skutterudite Ce1−xGdxFe4P12(x≈0.001), at temperatures where the host resistivity manifests a smooth insulator-metal crossover, provide evidence of the ...
Leading temperature dependence of the conductance in Kondo-correlated quantum dots
(IOP Publishing, 2018-03)
Using renormalized perturbation theory in the Coulomb repulsion, we derive an analytical expression for the leading term in the temperature dependence of the conductance through a quantum dot described by the impurity ...
Kondo resonances of transition-metal-atom impurities in a metal host: Dependence on d-orbital occupancy.
(APS Physics, 2008-12)
Kondo resonances for transition-metal-atom impurities in a metal host have been analyzed by means of an ionic model as a function of the impurity d-orbital occupancy. The ionic Hamiltonian has been obtained by making use ...
Kondo temperature when the Fermi level is near a step in the conduction density of states
(American Physical Society, 2017-01-27)
The (111) surface of Cu, Ag, and Au is characterized by a band of surface Shockley states with a constant density of states beginning slightly below the Fermi energy. These states as well as bulk states hybridize with ...
