Abstract:

Under the AASERT program, our student developed magnetically active II-VI diluted magnetic semiconductor DMS surface quantum well substrates upon which to epitaxially grow and pattern ferromagnetic Fe films in order to produce spin-dependent potentials. This material phase produced a variety of flux-focusing magnetic patterns including planar wedges and variable-spaced single domain particle arrays with nominally 0.1-0.5 micron feature sizes. These patterns are designed to create a field-driven spin-dependent energy landscape for optically-pumped or doped carriers and provide a basis for spatial measurements of electronic spin transport.
