terms-of-use Thomas, Andy Gönnenwein, Sebastian T. B. Magnetic Weyl semimetals exhibit intriguing transport phenomena due to their non-trivial band structure. Recent experiments in bulk crystals of the shandite-type Co<sub>3</sub>Sn<sub>2</sub>S<sub>2</sub> have shown that this material system is a magnetic Weyl semimetal. To access the length scales relevant for chiral transport, it is mandatory to fabricate microstructures of this fascinating compound. We therefore have cut micro-ribbons (typical size 0.3 X 3 X 50 μm<sup>3</sup>) from Co<sub>3</sub>Sn<sub>2</sub>S<sub>2</sub> single crystals using a focused beam of Ga<sup>2+</sup>-ions and investigated the impact of the sample dimensions and possible surface doping on the magnetotransport properties. The large intrinsic anomalous Hall effect observed in the micro-ribbons is quantitatively consistent with the one in bulk samples. Our results show that focused ion beam cutting can be used for nano-patterning single crystalline Co<sub>3</sub>Sn<sub>2</sub>S<sub>2</sub>, enabling future transport experiments in complex microstructures of this Weyl semimetal.
