Abstract
(, Ge, Ga) kagome Weyl semimetals have attracted significant research interest due to their large anomalous Hall, thermal, and optical effects originating from their nontrivial band topology. These large topological effects together with the antichiral antiferromagnetic order that can be manipulated through various experimental means provide unique platforms for developing high-speed spintronics. is known to have the largest Néel temperature ( K), which is useful for developing antiferromagnetic spintronics. Here, we establish the epitaxial growth of antiferromagnetic films by magnetron sputtering and present their structure, magnetotransport, terahertz properties, and exchange bias effect in /NiFe bilayers, establishing their remarkable properties essential for future investigations towards device applications.
