Abstract

In combining magneto-transport investigations with NMR (nuclear magnetic resonance) we measured the effect of the nuclear hyperfine field B H F on quantum oscillations in the transverse magneto-resistivity ρ xx and in the Hall resistivity ρ xy of metallically doped n-InSb. Quantitative analysis of the B H F-induced change in ρ xx demonstrates that this experiment allows to separate spin splitting phenomena in magneto-transport from effects due to the external magnetic field B. This is used to show that an oscillatory structure in R H xy /B is directly related to a redistribution in the occupation of the two spin states in the lowest Landau level.
