Abstract

In order to realize magnetic nanocrystals for spin electronic devices, we have successfully grown MnAs and/or MnSb nanocrystals on atomically controlled GaAs(001) substrates by molecular beam epitaxy. Surface structures of sulfur- and antimony-terminated GaAs substrates are characterized by synchrotron radiation soft X-ray standing waves. Then, Mn pnictide nanocrystals are grown by super Volmer-Weber epitaxy, taking advantage of low surface energy. MnAs and/or MnSb nanocrystals grown on sulfur-terminated GaAs(001) substrates show ferromagnetic properties with size of 20-30 nm and surface density of more than 10¹⁰ cm^-2 spectroscopy revealed the electronic structures of these magnetic dots.
