| Popis: | The superconducting dome of most iron-based superconductors emerges from a phase with nematic and magnetic ordering. However, the multiband and multiorbital nature of iron-based superconductors as well as twinning effects pose challenges to fully characterize the implications of these two ordering phenomena for the band structure. Here, the authors report high-quality ARPES measurements on twinned and detwinned BaFe${}_{2}$As${}_{2}$ and present a comprehensive and systematic overview of the band structure in the normal and the magnetically ordered states of this prototype parent compound. |
