摘要：

In Al(x)Ga(1-x)As/GaAs heterostructures the NMR and the Knight shift of Ga-69, Ga-71 and As-75 has been detected optically due to the enhanced sensitivity compared to conventional NMR. From the Knight shifts results a ratio 1.4 of the conduction electron (psi-(r(k)))2 on the V- and III-site. The nuclear spin lattice relaxation times for each nuclear species were determined separately. These times are discussed in comparison with results from other measurements.
