title = "Fermi surface topology of Ca1.5Sr0.5RuO4 determined by angle-resolved photoelectron spectroscopy",
abstract = "The angle resolved photoelectron spectroscopy of the Fermi surface of Ca1.5Sr0.5RuO4 at the boundary of magnetic /orbital instability in the phase diagram of C substituted Sr ruthenates was investigated. It was observed that at at higher Sr concentrations (0.2< x < 0.5), the system became a paramagnetic metal and the superconductivity emerged at x = 2. Three energy bands and the corresponding Fermi surface sheets were found. The observation of the three Fermi surface sheets in Ca 1.5Sr0.5RuO4 and the lack of significant interorbital electron transfer demonstrated the absence of orbital-selective Mott transition (OSMT) in this material.",
