Fermi surface of the parent compound of iron-based superconductor

ORAL

Abstract

Fermi surface of the parent compound of iron-based superconductor BaFe2As2 is studied by angle-resolved photoemission spectroscopy using VUV-laser. This compound shows structural and magnetic phase transition around TN = 140 K [1]. We found the transformation of Fermi surface across TN. We will discuss its origin comparing with the first principle band calculation. \\[4pt] [1] M. Rotter et al., Phys. Rev B 78, 020503 (2008).
