Nuclear magnetic resonance (NMR) has been used to probe the atomic displacements and bond bending around an isovalent impurity (In) in the GaAs lattice. It is concluded that the In atoms substitute on the Ga sublattice, that they do not cluster, and that the strain field induced by these isolated atoms is sufficient to affect the NMR of arsenic atoms as far away as 30 Ã…. Estimates of bond angle distortions in the nearest atomic shells around the In atom are discussed.

    We have detected nuclear magnetic resonance in GaAs by selectively inverting 71Ga spins to create a local force gradient which shifts the mechanical resonance frequency of a nearby magnet tipped microcantilever. Employing a low spring constant cantilever (60 μN/m) at 4.4 K and 7 T, we...

    We studied the transport of photoinjected spins in GaAs by time-resolved photoluminescence measurements. At low temperatures, the spin polarization after drift transport of 4 μm is found to decrease as the applied electric field E increases to a few kV/cm, and it disappears when E exceeds 3...
