Two‐level systems in disordered metals can contribute to the \documentclass{article}\pagestyle{empty}\begin{document}$ \sqrt T $\end{document} resistivity anomaly at low temperatures, by reducing the resistivity increment due to weak localization. A comparison is made with the generally larger effects expected from electron‐electron correlations, and with data for Mg‐Zn glassy metals.
