Keywords: | g-factor; Parallel magnetic field; Spin | Issue Date: | 2001 | Journal Volume: | 64 | Journal Issue: | 23 | Start page/Pages: | 2333191-2333193 | Source: | Physical Review B - Condensed Matter and Materials Physics | Abstract: | We report low-temperature magnetoresistivity measurements of high-quality gated two-dimensional (2D) electron systems. In the dilute electron density limit, we show evidence for spin polarisation in an in-plane magnetic field. Using a simple model, we estimate the Landé g-factor in this dilute two-dimensional electron gas to be about 3.32. The enhanced Landé g-factor compared with that of a bulk GaAs 2D electron system (0.44) is ascribed to electron-electron interaction effects at ultra-low electron densities. © 2002 Elsevier Science B.V.
