Epitaxial growth and characterization of Mn₂Au thin films for antiferromagnetic spintronics — •Helge Bräuning, Mathias Kläui, and Martin Jourdan — Institut für Physik, Johannes Gutenberg Universität, Staudingerweg 7, 55128 Mainz, Germany

The antiferromagnetic compound Mn₂Au is characterized by large spin-orbit coupling, which makes it a promising material for novel antiferromagnetic spintronics (see e.g. [Bar13, Zel14]).

We prepared thin films of Mn₂Au by RF-sputtering from a stoichiometric target on MgO and Al₂O₃ substrates using different buffer layers. Epitaxial samples with different growth directions such as [100], [001], and [101], were obtained. The samples were characterized by x-ray diffraction, magnetometry, AFM and SEM. Additionally, magnetotransport investigations will be presented.
