Abstract

Understanding the electrical manipulation of the antiferromagnetic order is a crucial aspect to enable the design of antiferromagnetic devices working at THz frequencies. Focusing on collinear insulating antiferromagnetic NiO/Pt thin films as a materials platform, we identify the crystallographic orientation of the domains that can be switched by currents and quantify the Neél-vector direction changes. We demonstrate electrical switching between different T domains by current pulses, finding that the Neél-vector orientation in these domains is along [±5 ±5 19], different compared to the bulk â ¨112â
