Growth of epitaxial (110) oriented Mn2Au thin films via Molecular Beam Epitaxy — •Daniel Casey, Daragh Mullarkey, and Igor V. Shvets — School of Physics, Trinity College Dublin, The University of Dublin, Dublin 2, Ireland

Here we explore the crystallographic nature and growth of antiferromagnetic Mn2Au (110) oriented thin films deposited by molecular beam epitaxy.

By co-evaporating Mn and Au from separate Knudsen cells, (110) oriented films were obtained when deposited on a Pt (111) seed layer on Al2O3 (0001) substrates. A combination of high-resolution X-ray diffraction, low and high energy electron diffractions are used to elucidate the epitaxial relation of these films. The influence of substrate temperature during growth on the quality of the Mn2Au thin films is also explored.
