Antiferromagnetic Weyl semimetals based on Mn3X (X = Ge, Sn, Ga) kagome compounds exhibit significant electromagnetic responses even in the absence of large magnetization, but optimizing these effects across a wide temperature range is crucial for device applications. Here, the authors demonstrate that Mn3Sn1−xGax sputtered films offer tunable antiferromagnetic transition temperatures and enhanced anomalous Hall effect, paving the way for optimized antiferromagnetic materials in technological applications.
