Magneto-optical properties of semiconductor-based superlattices having GaAs with MnAs nanoclusters
We have fabricated semiconductor-based magnetic superlattices (SLs) containing GaAs:MnAs granular material in which MnAs nanoclusters are embedded in GaAs, and have characterized their structural, optical, and magneto-optical properties. SLs consisting of GaAs:MnAs and AlAs are shown to have good crystalline quality and excellent compatibility with nonmagnetic GaAs/AlAs heterostructures. The optical transmission properties were improved in the SLs, while keeping the strong magneto-optical properties of GaAs:MnAs. We used these magnetic SLs in a semiconductor-based magnetic microcavity as the central magnetic layer, and its optical transmission was found to have improved compared with our previous multilayer structures. {copyright} 2001 American Institute of Physics.
