Abstract

Magnetic ordering of the first row transition metal intercalates of NbS $_2$ due to coupling between the conduction electrons and the intercalated ions has been explained in terms of Fermi surface nesting. We use angle-resolved photoelectron spectroscopy to investigate the Fermi surface topology and the valence band structure of the quasi-two-dimensional layer compounds Mn $_{1/3}$ NbS $_2$ and Ni $_{1/3}$ NbS $_2$ . Charge transfer from the intercalant species to the host layer leads to non-uniform, pocket selective doping of the Fermi surface. The implication of our results on the nesting properties are discussed.
