Description

Magnetotransport properties of GaMnAs single layers and InGaMnAs/InGaAs superlattice structures were investigated at temperatures from 4 K to 300 K and magnetic fields up to 23 T to study the influence of carriers confinement through different structures. Both single layers and superlattice structures show paramagnetic-to-ferromagnetic phase transformation. In GaMnAs/InGaAs superlattice beside the Curie temperature (Tc ∼ 40 K), a new phase transformation is observed close to 13 K. (author)
