The anomalous magnetoresistance of a two-dimensional hole gas in inversion channels on a silicon surface has been studied experimentally for the first time. The results show that this anomalous magnetoresistance can be described completely by the theory based on scattering by superconducting fluctuations. The energy relaxation time of the holes is determined. It is concluded that the spin-orbit scattering of holes plays an important role.
