我们提出了准一维Au/Fe近藤线的相位相干时间τ upsi的测量，并将τ upsi的温度依赖性与最近的磁性杂质非弹性散射理论进行比较[物理评论快报]。93，107204（2004）10.1103/PhysRevLett.93.107204]。对于低至0.2T（K）的温度，得到了非常好的一致性。在近藤温度T（K）以下，相位相干时间的倒数在几乎十倍的温度上随温度线性变化。
We present measurements of the phase coherence time taupsi in quasi-one-dimensional Au/Fe Kondo wires and compare the temperature dependence taupsi of with a recent theory of inelastic scattering from magnetic impurities [Phys. Rev. Lett. 93, 107204 (2004)10.1103/PhysRevLett.93.107204]. 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.
