Fig. 3: Gate-tuned anomalous Hall and topological Hall effect in Fe0.28TaS2 nanoflake.

a A schematic of gate-induced proton intercalation. b Hall resistivity under different gate voltages. Topological Hall resistivity \({\rho }_{{xy}}^{T}\) are shadowed by the light purple colour. c Gate-dependent anomalous and topological Hall resistivity. Inset: a Hall-bar device on solid ion (proton) conductor (SIC).
