Abstract

We have studied the cyclotron resonance of electrons and holes in various types of InMnAs-based structures at ultrahigh magnetic fields. Our observations, in conjunction with an eight-band effective mass model including the s-d and p-d exchange interactions with Mn d-electrons, unambiguously suggest the existence of s-like and p-like delocalized carriers in all samples studied. The samples studied include Paramagnetic n-type In_1-xMn_xAs films (x ∼ 0.12) grown on GaAs, ferromagnetic p-type In_1-xMn _xAs films (x ∼ 0.025) grown on GaAs with Curie temperatures (T_C) > 5 K, paramagnetic n-type In_1-xMn _xAs/InAs superlattices, ferromagnetic p-type In_1-xMn _xAs/GaSb heterostructures (x ∼ 0.09) with T_C = 30-60 K, and ferromagnetic (In_0.53Ga_0.47)_1-xMn _xAs/In_0.53Ga_0.47As heterostructures (x ∼ 0.05) grown on InP with T_C up to 120 K.
