Kondo screening of the spin and orbital magnetic moments of Fe impurities in Cu
Abstract
We demonstrate by analysing a model dilute Kondo alloy that x-ray magnetic circular dichroism (XMCD) is able to evidence the Kondo regime. The temperature evolution of the d spin and orbital magnetic moments of Fe impurities in highly diluted Cu:Fe alloys is measured. XMCD is also a unique technique which enables the direct and separate measurement of the spin and orbital moments of a Kondo impurity.
