Petit, Florent and Sfaxi, Larbi and Lelarge, Francois and Cavanna, A and Hayne, M and Etienne, Bernard (1997) High-field spin-polarization transition in the Landau bands of quasi-2D electron gases with strong lateral modulation. Europhysics Letters, 38 (3). pp. 225-230. ISSN 0295-5075Full text not available from this repository.
2D electron gases, imbedded in a 1D lateral potential (in AlxGa1-xAs), made by a periodic modulation in alloy composition, are obtained by organized epitaxy on vicinal surfaces. The exchange enhancement of the Landau level spin splitting is inhibited up to a strong magnetic field (similar to 6T here). Low-temperature magneto-transport data revealing this effect cannot be explained by disorder but are fully consistent with the large potential gradients associated with the modulation amplitude.
