Abstract
We have shown that due to weak localization corrections, in the spin-split conduction band of quantum wells with zinc-blende structure, the electron spin relaxation rate due to the D'yakonov-Perel' mechanism decreases logarithmically with decreasing frequency. The spin diffusion coefficient also decreases. This is quite different from antilocalization behavior at large times of the particle diffusion and conductivity. Possible experimental detection is suggested.Keywords
