Abstract

We have fabricated diluted magnetic semiconductors (DMSs) based on organicinorganic layered perovskite-type compounds, in which multiple quantum well structures were formed. DMSs were synthesized by substituting a small fraction of the Pb2+ ions in the inorganic layers with Mn2+ or Cu2+. XRD, ESR, and magnetization results indicate that the samples form mixed crystals. The Mn-doped samples exhibited paramagnetism down to 10 K, whereas the Cu-doped samples exhibited ferromagnetism at temperatures lower than ca. 15 K. In addition, a clear exciton peak was observed in the absorption spectrum of each sample. These results indicate that selforganized DMS quantum wells were successfully fabricated.
