Two-dimensional (2D) Dirac bands and flat are characteristics of a kagome lattice. However, experimental studies on their electrical transport few, because three-dimensional (3D) bulk materials, consisting stacked 2D layers, dominate the transport. We report magnetoresistance (MR) study material, ${\mathrm{Co}}_{3}{\mathrm{Sn}}_{2}{\mathrm{S}}_{2}$. Based analysis temperature, magnetic field, f...
