Abstract

We report angle-resolved photoemission (ARPES) measurements,density functional and model tight-binding calculations on (Ba-214),an antiferromagnetic insulator.Ba-214 does not exhibit the rotational distortion of the Iroctahedra that is present in its sister compound (Sr-214),and is therefore an attractive reference material to study the electronic structure of layered iridates.We find that the band structures of Ba-214 and Sr-214 are qualitatively similar, hinting at the predominant role of the spin-orbit interaction in these materials.Temperature-dependent ARPES data show that the energy gap persists well above TN, and favor a Mott over a Slater scenario for this compound. © 2014 IOP Publishing and Deutsche Physikalische Gesellschaft.
