Abstract

We present results of the first optical and angle-resolved photoemission (ARPES) measurements on the bilayer (Sr1-xCax)3Ru2O7, or (Ca/Sr)327, system. While the real part of optical conductivity, σ1(ω), of Sr327 is similar to that of the high-Tc cuprates, σ1(ω) of Ca327 can be described almost entirely by a single broad Drude-like component. The ARPES results show a dramatic change of the low-energy electronic structure with increasing Ca doping from a normal band metal to a narrow-band marginally metallic phase with a critical behavior at x ≃ 0.33.
