英文摘要	Recently intensive efforts have been devoted to the emerging field of anti-ferromagnetic (AFM) spintronics, where ferromagnetic electrodes are substituted by antiferromagnets. This study investigates the anisotropic magnetoresistance (AMR) of epitaxial tetragonal antiferromagnetic bimetallic films: Mn2Au and Mn2Au/Fe bilayers. An anomalous AMR effect with additional peaks is observed. This study theoretically and experimentally demonstrates that the AFM spins of Mn2Au can be viewed and controlled at room temperature, and this is achievable with a notably relatively small magnetic field of 200 mT. Strong hybridization between Au and Mn, and strong modification of the intrinsic quadratic anisotropy of Mn2Au from interfacial biquadratic anisotropy result in an additional anomalous AMR component of 1%. The fi ndings suggest that Mn2Au films can be used in room temperature antiferromagnetic spintronics.
