摘要：
We report on the successful fabrication and characterization of ferromagnetic Fe/Tb multilayer contacts with perpendicular magnetic anisotropy (PMA) on the clean As-terminated surface of a GaAs(001)-based light-emitting diode (LED) structure. PMA was inferred from magnetometry and Fe-57 conversion electron Mossbauer spectroscopy. Such contacts are a potential candidate for optical detection of electron spin injection from the remanent magnetic state into the semiconductor. © 2004 Elsevier Ltd. All rights reserved.
