摘要：

We report on the electronic structure of the bilayer ruthenate Ca3Ru2O7 using high quality single-crystals grown by a floating-zone method which have the lowest residual resistivity so far achieved. The quantum oscillation, specific heat, and angle-resolved photoemission-spectroscopy (ARPES) measurements performed on these crystals establish that Ca3Ru2O7 is a quasi two-dimensional low-carrier metal with a density-wave instability.
