用弱局域化方法测量了Fe原子在Au中的磁散射随温度的变化。我们发现，在这个著名的近藤系统的特征温度T K≈ 1 K处，散射最大，具有很强的温度依赖性。这是一个新的和直接的实验方法来观察理论预测的Kondo最大值，类似于超导体中的对破缺实验。
The magnetic scattering of Fe atoms in Au is measured as a function of temperature in the range between 0.08 and 4 K by means of weak localization. We find a strong temperature dependence with maximum scattering at the characteristic temperature T K≈ 1 K of this well-known Kondo system. This is a new and direct experimental approach to observation of the theoretically predicted Kondo maximum and is analogous to pair-breaking experiments in superconductivity.
