We have made the ΓΏrst observation of cyclotron resonance in In1-xMnxAs alloys. Our data unambiguously show that the e ective mass of electrons systematically decreases with increasing Mn concentration x. Using an 8-band k β’ p method, we demonstrate that this mass reduction is a combined e ect of (1)
We have studied the electronic structure of Ga1-xMnxAs by angle-resolved photoemission spectroscopy. The e ect of Mn doping in GaAs was revealed as the formation of new states near the Fermi level, which originate from the Mn aceptor state, and are split from the valence-band maximum of the host GaA
