Phenomenon of Maximum and Minimum in the Resistivity of Cu-Mn Kondo Alloys at Low Temperatures

Abstract

Abstract:A New analysis of the electrical resistivity has been studied for Cu-Mn Kondo alloys, and it was found a solution like a logarithm power series between resistivity and temperature, which cover all ranges of maximum and minimum in the resistivity and all kinds of interactions at low temperatures. The s-d exchange integral J sd acting the main role in Kondo effect Phenomenon, J sd is negative or positive, according to a kind of interaction between conduction electron spins of the host normal metal and localized spins of the transition element. PACS: 75: 50, 75:10, 75: 40, 75: 30.
