Abstract

In this chapter, we review recent progress in angle-resolved photoemission spectroscopy (ARPES) studies of iron-pnictide superconductors, by particularly focusing on the experimental results on the BaFe₂As₂ system where the ARPES investigations have been most intensively performed. We discuss (i) the evolution of the Fermi surface topology upon electron- and hole-carrier doping, (ii) the superconducting-gap symmetry, (iii) the many-body interactions, and (iv) the electronic states in the antiferromagnetic phase of a parent compound, as well as their implications to the mechanism of superconductivity.
