Abstract :
Summary form only given. A femtosecond-resolved low-temperature near-field scanning optical microscope (NSOM) is used to monitor the spatio-temporal evolution of excitonic spins in a magnetic semiconductor, ZnSe-ZnCdSe MBE-grown semiconductor quantum well structures that are laterally patterned.
