 Electron Energy Relaxation in the Presence of Magnetic Impurities

Alexei Kaminsky

(Department of Physics, University of Maryland)

Abstract:  We study inelastic electron-electron scattering mediated by the exchange interaction of electrons with magnetic impurities. We find the kernel K of the corresponding two-particle collision integral. In a wide region of parameters, the kernel is proportional to the inverse square of the transferred energy E, K ~ 1/E2. These results provide a quantitative explanation of the experiments of Pothier et al. [Phys. Rev. Lett. 79, 3490 (1997)] on electron energy relaxation in short metallic wires.
