Materials with kagome lattice exhibit peculiar transport characteristics owing to the presence of nodal lines and loops within their electronic band structure

which bestows significant value for the investigation of quantum materials. Recently

the kagome structured schist compounds

have attracted considerable attention due to their novel topological properties. For instance

were successfully synthesized via the solid-state reaction method. A comprehensive set of measurements

including electrical resistivity

and magnetic properties

were performed on these samples. The resistivity curve of the Ni

single crystals exhibited a pronounced nonlinearity

reaching a maximum of 93% at T=6 K and B=7 T

and displayed a significant anisotropy. De Haas-van Alphen oscillations were observed in the magnetic measurements.
