Abstract = {{Using resonant inelastic x-ray scattering (RIXS) at the Cu L-absorption
   edge, we have observed intense, dispersive spin excitations in highly
   overdoped Tl2Ba2CuO6+delta (superconducting T-c = 6 K), a model compound
   whose normal-state charge transport and thermodynamic properties have
   been shown to exhibit canonical Fermi-liquid behavior. Complementary
   RIXS experiments on slightly overdoped Tl2Ba2CuO6+delta (T-c = 89 K) and
   on Y1-xCaxBa2Cu3O6+delta compounds spanning a wide range of doping
   levels indicate that these excitations exhibit energies and
   energy-integrated spectral weights closely similar to those of
   antiferromagnetic magnons in undoped cuprates, indicating the
   persistence of substantial antiferromagnetic spin correlations over a
   wide doping range. The surprising coexistence of such correlations with
   Fermi-liquid-like charge excitations in highly overdoped cuprates poses
   a challenge to current theoretical models of correlated-electron metals.}},
