Abstract
Carbon doped p‐type AlGaAs heterostructures are investigated by low‐temperature magnetotransport measurements. High quality of such two dimensional hole gases is demonstrated by observing sharp integer plateaus in Hall resistance as well as features of fractional quantum Hall effect at filling factors 4/3 and 5/3. The observed beating pattern of low‐field Shubnikov‐de Haas oscillations represents clear evidence for the existence of the two spin‐split subbands which arise from strong spin‐orbit coupling in hole systems.
