The Electrical Resistivity of Dilute AuCr Alloys. I. A Generalized Phase Shift Analysis of Kondo Effect

抄録

The electrical resistivity of dilute AuCr alloys (2∼320 at.ppm) was measured in a temperature range between 0.5 K and 300 K and the results were analyzed in terms of the generalized phase shift approach (GPS) developed by Soultie. A set of physical quantities representing the Kondo effect has been obtained.
The Kondo temperature and the magnetic moment of Cr impurity deduced from the resistivity data using the GPS model were compared with those determined by the nuclear orientation and the susceptibility experiments and a satisfactory agreement has been obtained.
