Weyl semimetals exhibit a unique feature known as Weyl nodes, which give rise to non-trivial topological features such as an anomalous Hall effect, and there are many efforts to try and control such properties. Here, the authors report light-induced

Magnetic Weyl semimetals, such as Co3Sn2S2, are ideal to realise anomalous transport properties based on the Berry curvature in the specific electronic bands and are expected to be useful for topological spintronics. Here, the authors investigate the

The coexistence of ferromagnetism and topology has recently attracted intense interest. Here, the thickness dependence of magnetisation and anomalous Hall conductivity is investigated in Co3Sn2S2 thin films, revealing a critical thickness of 10 nm fo

Co_{3}Sn_{2}S_{2} (CSS) is one of the shandite compounds and becomes a magnetic Weyl semimetal candidate below the ferromagnetic phase transition temperature (T_{C}). In this paper, we investigate the temperature (T) dependence of conversion between

Co-based shandite ${\mathrm{Co}}_{3}{\mathrm{Sn}}_{2}{\mathrm{S}}_{2}$ is a representative example of magnetic Weyl semimetals showing rich transport phenomena. We thoroughly investigate magnetic and transport properties of hole-doped shandites ${\ma

Magnetic Weyl semimetals are quantum phases of matter arising from the interplay of linearly dispersive bands, spin-orbit coupling, and time reversal symmetry breaking. This can be realised, for example, in Co3Sn2S2, based on a cobalt kagome lattice
