Abstract

It is well-known that in the Quantum-Hall (QH) regime the Shubnikov-de Haas (SdH) oscillations and the Hall resistance show a non-ohmic behaviour, which apparently is spin-dependent. We report on new measurements on this effect, which have been carried out with the help of a back-gate and by the use of the effect of persistent photoconductivity induced by light of out-gap energy.
