摘要：

The intrinsic spin Hall conductance shows rich sign changes by applying a perpendicular magnetic field in two-dimensional hole gas. Especially, notable sign changes can be achieved by adjusting the characteristic length of the Rashba coupling and hole density at moderate magnetic fields. The resonant intrinsic spin Hall conductance appears in high hole density and strong magnetic field due to the transition between mostly spin -1/2 holes and spin 3/2 holes is confirmed. Two likely ways to establish intrinsic spin Hall effect in experiments and a possible application are suggested. (c) 2006 American Institute of Physics.
