| dc.description.abstract | The existence of localized magnetic moments in dilute magnetic alloys that couple to the conduction electrons has important consequences for the electrical resistivity. The magnetic impurities act as scattering centers, and if they are the predominant type of impurity then at low enough temperature the scattering causes the electrical resistivity. The exchange interaction between the conduction and the localized moments leads to scattering events in which the electron spin is flipped. Calculating the transition probabilities of the conduction electrons to the third order of interaction it is shown that the transition probability has a logarithmic anomaly at the Fermi-surface and that in the resistivity there appears a term proportional to lnT and diverges as the temperature approaches zero. | en_US |
