摘要

We report measurements of spin susceptibility of a two-dimensional hole gas confined at an GaAs/AlGaAs interface in density range from 2.8 X 10(10) to 6.5 X 10(10) cm(-2). We used the method of spin polarization of carriers in parallel magnetic field. We observed an enhancement of the spin susceptibility over the bulk value that increases as the density is decreased in qualitative agreement with Quantum Monte Carlo calculations. The measured enhancement factor increases from 2.5 to 4.8 as the hole density is decreased. (c) 2005 Elsevier Ltd. All rights reserved.
