Abstract

The Zeeman effect of a hybrid structure consists of a ZnCdMnSe diluted magnetic semiconductor (DMS) quantum well (QW) and superconductor array pattern on the surface was investigated by magneto-photoluminescence (PL) experiment. The superconductor arrays were designed to have width and space of 20 and of 2 μm, respectively. The PL from DMS-QW exhibits a large Zeeman shift, a characteristic of DMS system, in the presence of a magnetic field. Significant enhancement of the Zeeman shift, however, was observed in the PL emitted from the superconductor patterned area compared to that observed from un-patterned area of DMS-QW. This indicates that the superconductor arrays pattern enhances the strength of applied magnetic field for local patterned area of the DMS-QW system.
