Abstract

A magnetooptical approach aimed at probing the optical response of a diluted magnetic semiconductor to the fringe field of nanostructured ferromagnets with subμm spatial resolutions was presented. A micromagnetoluminescence spectroscopic analysis with a submicron spatial resolution was performed in order to probe the semiconductors PL signal beneath the ferromagnetic structures. On scanning a CdZnMnSe/ZnSe quantum well covered by a single 700 nm wide dysprosium wire, a redshift of the magnetoresistance was found beneath the ferromagnetic stripe. The phenomena exhibited the presence of a local band gap modulation due to the giant Zeeman effect caused by the fringe field of ferromagnetic nanostructures.
