Magnetic domain engineering in antiferromagnetic CuMnAs and Mn$_2$Au devices
Abstract
Antiferromagnetic (AF) materials hold potential for use in spintronic devices with fast operation frequencies and robustness against magnetic field perturbations. However, the precise tuning of material properties such as magnetic anisotropy and domain structure is crucial for efficient device functionality, yet poorly understood in fully compensated antiferromagnets. This study clarifies the mechanisms governing domain formation in antiferromagnetic devices by investigating the AF domains in patterned structures fabricated from CuMnAs and Mn$_2$Au thin films, which are key materials in antiferromagnetic spintronics research. The results reveal that patterned edges have a significant impact on the magnetic anisotropy and AF domain structure over long ranges, which can be modeled through the consideration of short-range edge anisotropy and long-range magnetoelastic interactions. The non-trivial interaction of magnetostriction, substrate clamping, and edge anisotropy leads to specific equilibrium AF domain configurations in devices. This study explores the use of antiferromagnetic domain engineering through patterning to enhance device performance in both CuMnAs and Mn$_2$Au materials, which are the only known materials clearly associated with Néel spin orbit torques. By comparing two materials with the same magnetocrystalline symmetry but different elastic and magnetic anisotropy constants, the study disentangles the magnetic and elastic interactions which result in specific antiferromagnetic domain formation. These principles are applicable to all antiferromagnetic films grown on non-magnetic substrates as required for applications.
