# Exchange biased Anomalous Hall Effect driven by frustration in a magnetic Kagome lattice

## TL;DR

This paper demonstrates that in Co3Sn2S2, the interplay of topological properties and magnetic frustration in a Kagome lattice induces a strongly exchange biased anomalous Hall effect, revealing complex magnetic textures.

## Contribution

It introduces the novel observation of exchange bias in the anomalous Hall effect driven by magnetic frustration in a Kagome lattice topological semimetal.

## Key findings

- Exchange biased anomalous Hall effect observed in Co3Sn2S2.
- Coexistence of ferromagnetic and spin glass phases due to geometric frustration.
- Magnetic frustration influences topological transport properties.

## Abstract

Co3Sn2S2 is a ferromagnetic Weyl semimetal that has been the subject of intense scientific interest due to its large anomalous Hall effect. We show that the coupling of this material's topological properties to its magnetic texture leads to a strongly exchange biased anomalous Hall effect. We argue that this is likely caused by the coexistence of ferromagnetism and spin glass phases, the latter being driven by the geometric frustration intrinsic to the Kagome network of magnetic ions.
