Abstract

We have successfully grown and characterized [Fe/Tb]₁₀ /Fe (001) / ⁵⁷Fe (001) /MgO (001) multilayer contacts on a GaAs-based light emitting diode. Using ⁵⁷Fe conversion-electron Mössbauer spectroscopy at room temperature (RT) and at 4.2 K, we provide atomistic proof of large perpendicular Fe spin components in zero external field at and below RT at the ⁵⁷Fe (001) /MgO (001) interface. Further, indirect evidence of large interfacial Fe atomic moments is provided. Our contacts serve as a prototype spin aligner for remanent electrical spin injection at RT.
