Single crystals of CoSn lightly doped with Fe, In, or Ni are investigated using x-ray and neutron scattering, magnetic susceptibility and magnetization, ac susceptibility, specific heat and resistivity measurements. Within the rigid band approximation, hole doping with a few percent of Fe or In should move the flat bands closer to Ef, whereas electron doping with Ni should move the flat bands further away from Ef. We provide evidence that this indeed occurs. Fe and In doping drive CoSn tow","authors_text":"A. D. Christianson, A. F. May, B. C. Sales, J. -Q Yan, J. Xing, M. A. McGuire, M. B. Stone, Q. Zhang, S.
