Abstract
This study deals with the effect of electron scattering by impurities with localized magnetic moments on the electrical conductivity of a metal microcontact. It is demonstrated that the second derivative of the current with respect to the voltage (microcontact spectrum) contains a nonlinearity in the low-voltage range eV ∼ T (zero bias anomalies). The sign of a zero bias anomaly is determined by the sign of the exchange integral J.Keywords
