摘要: In Kondo systems, de Haas-van Alphen experiments determine a spin-splitting term in the conduction-electron self-energy. It is shown that for all temperatures and magnetic fields, presence of normal potential scattering from impurity, Landau levels given exactly with Re Sigma spindown(0)-Re spinup(0)=cJ(Sz)K sigma (0) self energy at Fermi level (Sz)K expectation value impurity spin including effects. This equation also applies both large-U (Kondo) small-U limits Anderson model, to (Sz)A case. (Sz)K,A does not obey field temperature dependence Brillouin function, but instead follows Langevin function. so because Friedel-Anderson d orbitals are populated successively by many electrons during impurity-spin relaxation time.
