Hybrid structures consisting of submicron ferromagnetic dysprosium wires on a diluted magnetic semiconductor quantum well have been prepared and investigated by micro-magnetoluminescence spectroscopy. A magnetic field dependent redshift of the semiconductor band gap just beneath the dysprosium wires with respect to a reference area clearly demonstrates the impact of the magnetic fringe field on the optical properties of the underlying semiconductor. © 2004 American Institute of Physics.

    The field spectrum linewidth of a multiple quantum well laser immersed in a high magnetic field is measured at room temperature and at 165 K. The low-temperature measurements show a decrease of linewidth with increasing magnetic field. We believe this behavior results from the formation of a...
