“…As a consequence of good crystal quality and variety of compounds, the 122 family is the most studied by ARPES [37] (see [38][39][40][41][42][43][44] for BKFA, [28,[45][46][47][48][49] for BFCA, [29,[50][51][52][53] for BFA, [31,54] for KFA, [29,55] for CaFe 2 As 2 , [56,57] for BFAP, [58] for EuFe 2 (As 1-x P x ) 2 ). The ARPES spectra well represent the bulk electronic structure of this family, at least, for the hole doped BKFA, BNFA, and BFAP, where the superconducting gap is routinely observed [39,41,59] and is in a good agreement with the bulk probes [43,44].…”
