  We consider the potential for novel forms of magnetism arising from the
subtle interplay between electrons and spins in the under-screened kagome Kondo
lattice model. At weak coupling, we show that incommensurate non-coplanar
multi-wave vector magnetic orders arise at nearly all fillings and that this
results from Fermi surface effects that introduces competing interactions
between the spins. At strong coupling, we find that such complex order survives
near half filling despite the presence of ferromagnetism at all other fillings.
We show this arises due to state selection among a massive degeneracy of states
at infinite coupling. Finally, we show that at intermediate filling, only
commensurate orders seem to survive. But these orders still include
non-coplanar magnetism. So, the mere presence of both local moments and
itinerant electrons enables complex orders to form unlike any currently
observed in kagome materials.
