Interplay of magnetic frustration and topology in complex metals*

The interplay of topology and frustration can lead to exotic properties and physical phenomena. We study how signatures of topological transport properties can be affected by complex magnetic textures in Kagome and triangular lattice materials. As an example, we show in the case of Co3Sn2S2 that the presence of frustration leads to coexsiting magnetic phases that drive an exchange biased anomalous Hall effect. We also study novel transport anisotropies and magnetoelectric coupling in microstuctured devices.
