Abstract: Spin related phenomena in quantum nanostructures have attracted recently much interest due to fast growing eld of spintronics. In particular complex nanostructures are important as they provide a versatile system to manipulate spin and the electronic states. Such systems can be used as spin memory devices or scalable quantum bits. We investigate the spin relaxation for an electron in a complex structure composed of a quantum dot surrounded by a quantum ring. We shown that modi cations of the con nement potential result in the substantial increase of the spin relaxation time.
