Abstract

We have performed high-resolution angle-resolved photoemission spectroscopy (ARPES) of the borocarbide superconductor YNi2B2C to study the Fermi surface (FS) topology of the anisotropic s-wave superconductor. We successfully observed experimental valence band dispersions and Fermi surfaces (FSs), and indicated two nested parts connected by the known nesting vector Q∼(0.55,0,0).
