SPIN-ORBIT SCATTERING AND THE KONDO EFFECT

The effects of spin-orbit scattering of conduction electrons in the Ko ndo regime are investigated theoretically. It is shown that due to tim e-reversal symmetry, spin-orbit scattering does not suppress the Kondo effect, even though it breaks spin-rotational symmetry, in full agree ment with experiment. An orbital magnetic field, which breaks time-rev ersal symmetry, leads to an effective Zeeman splitting, which can be p robed in transport measurements. It is shown that, similar to weak loc alization, this effect has anomalous magnetic-field and temperature de pendence.
