Weak localization in spin-glass systems

Abstract
By performing the calculation for weak localization in spin-glass systems, we have found that randomly fixed spins dephase weak localization. The dephasing magnetic-scattering rate is reduced by a factor of S/(S+1), compared with the free-magnetic-moment system. We have also studied the uniaxial spin glass where the spins are either parallel or antiparallel to the z axis. Here the role of spin-orbit scattering is crucial in the dephasing.
