We report the observation of commensurability oscillations, induced by a one-dimensional periodic potential, in a high-mobility GaAs two-dimensional hole system confined to a triangular quantum well. The measured oscillations exhibit two frequencies that agree well with those calculated from the Fermi contours of the two spin-split hole subbands, providing clear evidence for the observation of spin-resolvedcommensurability oscillations.
