Having the advantages of immunity to external magnetic fields and fast spin dynamics, antiferromagnetic materials open a new door towards the next generation of high-speed data storage devices. Here, we optimized the growth condition of epitaxial Mn2Au and NiO films, an antiferromagnetic metal and an insulator film, which can be controlled electrically with two different spin-orbit torque mechanisms [Ref.1, ref.2]. The materials are consequently patterned into star shaped devices for electrical switching measurements. Due to current-induced switching of Neel vectors, we observe a change of Anisotropic Magnetoresistance (AMR). This Neel vector switching offers a platform to investigate magnetization dynamics in antiferromagnetic materials.
