Abstract
We determined the nuclear-spin-lattice relaxation rate in the vicinity of the two-dimensional electrons in GaAs heterostructures at liquid-helium temperatures in the magnetic-field range 4<B<8.5 T. The occurring magnetoquantum oscillations are, by a model calculation, proved to be due to interaction between nuclear and 2D-electronic spins (Korringa relaxation), and give new information on the electronic density of states.Keywords
