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.
