Epitaxial growth of ferromagnetic Ni_(2)MnIn on (001) InAs

摘要

The ferromagnetic Heusler alloy Ni_(2)MnIn has been grown on InAs (001) by molecular-beam epitaxy. In situ reflection high-energy electron diffraction, ex situ x-ray diffraction, Rutherford backscattering spectrometry, and transmission electron microscopy indicate the high-quality epitaxial growth of Ni_(2)MnIn with the B2 crystal structure on InAs (001). Superconducting quantum interference device magnetometry shows that the Ni_(2)MnIn film is ferromagnetic with a Curie temperature ～170K.
