Query: Fermi surface topology and low-lying electronic structure of a new
  iron-based superconductor Ca10(Pt3As8)(Fe2As2)5   We report a first study of low energy electronic structure and Fermi surface
topology for the recently discovered iron-based superconductor
Ca10(Pt3As8)(Fe2As2)5 (the 10-3-8 phase, with Tc = 8K), via angle-resolved
photoemission spectroscopy (ARPES). Despite its triclinic crystal structure,
ARPES results reveal a fourfold symmetric band structure with the absence of
Dirac-cone-like Fermi dots (related to magnetism) found around the Brillouin
zone corners in other iron-based superconductors. Considering that the
triclinic lattice and structural supercell arising from the Pt3As8 intermediary
layers, these results indicate that those layers couple only weakly to the FeAs
layers in this new superconductor, which has implications for the determination
of its potentially novel pairing mechanism.
