Abstract
Subject headings
Close
- 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 transition. In GaMnAs/InGaAs superlattice beside the Curie temperature (T-c approximate to 40 K), a new phase transition is observed close to 13 K.
