Non-exponential spin relaxation in magnetic field in quantum wells with random spin-orbit coupling

open access: yes, 2005
We investigate the spin dynamics of electrons in quantum wells where the Rashba type of spin-orbit coupling is present in the form of random nanosize domains. We study the effect of magnetic field on the spin relaxation in these systems and show that the
