Abstract

Europium chalcogenides are important magnetic semiconductors that have a potential for applications in spintronic devices. Here we shall investigate EuTe and EuSe epitaxial layers, grown by molecular beam epitaxy, to gather new experimental evidence that will improve our understanding of the electronic processes in these systems. The experiments that will be performed include time-resolved Faraday rotation, time-resolved photoluminescence and second harmonic generation. The research aims at detecting and controlling the electronic and lattice magnetism by the use of light. InAs quantum dots embedded in a GaAs matrix, and containing imprisoned electrons, grown by MBE at the University of Sao Paulo, shall also be investigated by time-resolved pump-probe Faraday rotation, to characterize their spintronic properties.
