Abstract
The magnetic scattering rates of dilute Co atoms both on the surface and in the bulk of Cu have been investigated by the method of weak localization. For Co on the surface of Cu the temperature dependence of the magnetic scattering rate shows a clear maximum at 23 K. This demonstrates that Co on the surface of Cu is a Kondo system with a Kondo temperature =23 K. However, covering the CO with about three atomic layers of Cu removes the magnetic scattering.
