## Abstract Spinβlattice relaxation mechanisms of nuclear spins in solids in the presence of low concentrations of paramagnetic centers are discussed. Apart from the electron spinβlattice relaxation mechanism, threeβspin processes involving two electron spins and a nuclear spin may also play a role
We report the polarization spectra obtained from strained \(I n_{x} G a_{1-x}\) As/GaAs quantum wells. They reflect two important microscopic properties : first, the spin relaxation of the photo-excited holes is incomplete during recombination; second, the spin relaxation of the photo-generated carr
