Susceptibility and Resistivity Studies of Localized Iron Moments in Copper

Abstract
Susceptibility measurements in fields from a few Oe to 1 kOe at temperatures down to 40 m°K show that the moment on the iron site is completely compensated at temperatures far below the Kondo temperature, at least at the high-field values. Correlation of these results with Mössbauer measurements reveals new information about the behavior of the low-temperature state formed in these alloys. The experimental technique used is discussed in detail. Some other properties of the copper-iron system are reviewed.
