Photoemission study of iron-based superconductor

The iron-based superconductivity （IBSC） is a great challenge in correlated system. Angle-resolved photoemission spectroscopy （ARPES） provides electronic structure of the IBSCs, the pairing strength, and the order parameter symmetry. Here, we briefly review the recent progress in IBSCs and focus on t...

Description
Summary:The iron-based superconductivity （IBSC） is a great challenge in correlated system. Angle-resolved photoemission spectroscopy （ARPES） provides electronic structure of the IBSCs, the pairing strength, and the order parameter symmetry. Here, we briefly review the recent progress in IBSCs and focus on the results from ARPES. The ARPES study shows the electronic structure of ＂122＂, ＂111＂, ＂11＂, and ＂122＂＂ families of IBSCs. It has been agreed that the IBSCs are unconventional superconductors in strong coupling region. The order parameter symmetry basically follows s form with considerable out-of-plane contribution.
