We have revealed the phase diagram of Ca 2− x Sr x RuO 4: the quasi-two-dimensional Mott
transition system that connects the Mott insulator Ca 2 RuO 4 with the spin-triplet
superconductor Sr 2 RuO 4. Adjacent to the metal/nonmetal transition at x≃ 0.2, we found an
antiferromagnetically correlated metallic region where non-Fermi-liquid behavior in
resistivity is observed. Besides this, the critical enhancement of susceptibility toward the
region boundary at xc≃ 0.5 suggests the crossover of magnetic correlation to a nearly …
