摘要：

In quasi-two-dimensional (2D) hole systems with an effective spin j=3/2, heavy-hole-light-hole splitting results in a quantization of angular momentum perpendicular to the 2D plane. The spin polarization of quasi-2D hole systems due to an in-plane magnetic field B-parallel to thus competes with the heavy-hole-light-hole splitting. As a result, the spin polarization of hole systems is very different from the spin polarization of j=1/2 electron systems. In particular, it is shown that the spin polarization of quasi 2D heavy hole systems can change its sign at a finite value of B-parallel to.
