Experimental test of the numerical renormalization-group theory for inelastic scattering from magnetic impurities -: art. no. 266805

We present measurements of the phase coherence time tau(phi) in quasi-one-dimensional Au/Fe Kondo wires and compare the temperature dependence of tau(phi) with a recent theory of inelastic scattering from magnetic impurities [Phys. Rev. Lett. 93, 107204 (2004)]. A very good agreement is obtained for temperatures down to 0.2T(K). Below the Kondo temperature T-K, the inverse of the phase coherence time varies linearly with temperature over almost one decade in temperature.
