Spin Susceptibility of an Ultra-Low Density Two Dimensional Electron System

J. Zhu, H. L. Stormer, L. N. Pfeiffer +2

We determine the spin susceptibility in a two dimensional electron system in GaAs/AlGaAs over a wide range of low densities from 2$\times 10^9$cm${}^{-2}$ to 4$\times 10^{10}$cm$^{-2…
