Abstract

The Weyl semimetal Co$$_{3}$$ 3 Sn$$_{2}$$ 2 S$$_{2}$$ 2 exhibits a combination of magnetic ordering with a large anomalous Hall effect. Lachman et al. find an intrinsic exchange bias of this anomalous Hall effect and attribute it to the coexistence of ferromagnetism and spin glass behaviour.
