چکیده
We repeat our previous calculation about the effect of the spin-orbit-induced magnetic anisotropy on the Kondo temperature in the case of S = 5/2 impurity spin which is quite different from the integer spin case as the ground state is degenerated. In this case the Kondo contribution remains finite when the sample size goes to zero and the thickness dependence in the Kondo resistivity is much more weaker for Cu(Mn). The behavior of the Kondo coefficient as a function of the thickness depends on the Kondo temperature, the thickness dependence is somewhat stronger for larger T K. Comparing our results with a recent experiment in thin Cu(Mn) films, we find a good agreement.

Spin-orbit scattering of Pb and Bi impurities in Cs, K, and Na films
The spin-orbit scattering ~SOS! of the Pb and Bi impurities in Cs, K, and Na films is measured by means of weak localization. The dimensionless SOS cross section for Pb in Cs ~in units of 4p/kF 2 ! has the large value of sso *' 2 3 . This SOS cross section is the absolute maximum possible for ~s,p! impurities ~if one neglects d and larger l scattering!. The SOS contributes almost 50% to the tot...

The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...
متن کاملSize Dependence In The Disordered Kondo Problem
We study here the role randomly-placed non-magnetic scatterers play on the Kondo effect. We show that spin relaxation effects (with time τ o s ) in the vertex corrections to the Kondo self-energy lead to an exact cancellation of the singular temperature dependence arising from the diffusion poles. For a thin film of thickness L and a mean-free path l, disorder provides a correction to the Kondo...

Motivated by the fact that the low-energy properties of the Kondo model can be effectively simulated in spin chains, we study the realization of the effect with bond impurities in ultracold bosonic lattices at half-filling. After presenting a discussion of the effective theory and of the mapping of the bosonic chain onto a lattice spin Hamiltonian, we provide estimates for the Kondo length as a...
