Intercorrelated anomalous Hall and spin Hall effect in kagome-lattice Co3Sn2S2 -based shandite films

This work establishes the pivotal role of topological bands in the magnetic Weyl semimetal prototype Co${}_{3}$Sn${}_{2}$S${}_{2}$ for efficient generation of spin current at room temperature via the spin Hall effect. Electron and hole-doped shandite films are systematically studied to map the evolution of Hall conductivities against Fermi level tuning. The authors demonstrate that the observed anomalous Hall conductivity and spin Hall conductivity maxima at distinct doping levels share the common origin in the band structure, suggesting such a correlation can be exploited for screening materials with large transverse magnetoelectric responses.
