The chiral antiferromagnet Mn₃Sn epitaxial thin film offers sunique opportunities in spintronics research due to its strong Berry curvature driven response, though its magnetic properties near interfaces remain largely unexplored. Here, the authors employ x-ray magnetic circular dichroism and demonstrate the uniform magnetic structures throughout the Mn₃Sn layer, from bottom to top interfaces in the W/Mn₃Sn/MgO multilayer. This research underscores the intrinsic nature of previously reported spin-torque phenomena, paving the way for the accelerated development of innovative spintronic devices.
