Abstract
We have studied spin-flip transitions between Zeeman sublevels in GaAs elec tron quantum dots. Several different mechanisms which originate from spin-o rbit coupling are shown to be responsible for such processes. It is shown t hat spin-lattice relaxation for the electron localized in a quantum dot is much less effective than for the free electron. The spin-flip rates due to several other mechanisms not related to the spin-orbit interaction are also estimated.
