On the electron scattering and dephasing by the nuclear spins

Dyugaev, A. M. · Vagner, I. D. · Wyder, P.

Original · EN

We show that scattering of the conduction electrons by nuclear spins via the hyperfine interaction may lead the upper limit on the mean free path in clean metals. Nuclear spins with s >1/2 may cause a strong dephasing in dirty limit due to the quadrupole coupling to the random potential fluctuations caused by static impurities and lattice imperfections.
