T-dependent EDCs (a) and their symmetrized form (b) of x = 0.2 integrated over the 0.4 ≤ kx ≤ 0.5 region (around the β-band, region #2 in Supplementary Fig. 2e). The raw ARPES data are also shown in Supplementary Fig. 2e. c Near EF spectral weight (ΔE = ± 20 meV) of the symmetrized EDCs in b as a function of T. TKH is determined to be 45 (±8) K. Schematics of the spin structure and corresponding electronic structure of the β- and γ-bands in three different cases: d without OSMP and KH, e with OSMP but without KH and f with both OSMP and KH.
