The effects of reduced dimensionality an quantum confinement on fundamental magnetic and electronic spin dynamics are being investigated in quantum structures fabricated from II-VI diluted magnetic semiconductors (DMS). Magneto-optical spectroscopy probes spin-dependent phenomena such as carrier spin-flip scattering, spin dependent electronic tunneling and localization, magnetic polaron formation, and spin-lattice relaxation processes. The program combines state-of-the-art techniques in femtosecond optical measurements, integrated DCSQUID technology and epitaxial materials fabrication to obtain a real-timed view of dynamical behavior in quantum magnetic systems.
