Phys. Rev. Lett. 95, 037001 (2005) [4 pages]Magnetic Correlations in the Hubbard Model on Triangular and Kagomé LatticesReceived 14 February 2005; published 13 July 2005 In order to study the magnetic properties of frustrated metallic systems, we present, for the first time, quantum Monte Carlo data on the magnetic susceptibility of the Hubbard model on triangular and kagomé lattices. We show that the underlying lattice structure determines the nature and the doping dependence of the magnetic fluctuations. In particular, in the doped kagomé case we find strong short-range magnetic correlations, which makes the metallic kagomé systems a promising field for studies of superconductivity. © 2005 The American Physical Society URL:
