Abstract :
Low-temperature magnetotransport measurements and far-infrared transmission spectroscopy are reported in molecular beam epitaxial grown two-dimensional hole systems confined in strained InAs quantum wells with magnetic impurities in the channel. The interactions of the free holes spin with the magnetic moment of 5/2 provided by manganese features intriguing localization phenomena and anomalies in the Hall and the quantum Hall resistance. In magnetic field-dependent far-infrared spectroscopy measurements well-pronounced cyclotron resonance and an additional resonance are found that indicates an anti-crossing with the cyclotron resonance.
