In the study of oscillatory electron transport in high-mobility Si MOSFETs at low temperatures we observed two correlated effects in weak in-plane magnetic fields: a steep decrease of the magnetic susceptibility χ(H) and an increase of the concentration of mobile carriers n(H). We suggest a phenomenological model of the magnetic-field-driven redistribution between the extended and localized electronic states that qualitatively explains both effects. We argue that the redistribution is mainly… Expand

On the role of disorder in transport and magnetic properties of the two-dimensional electron gas
We describe the effects of disorder in a two-dimensional electron gas in the presence of a parallel magnetic field. We argue that localized states lead to the formation of local moments. The parallelExpand
