a, b Spin-resolved EDCs and spin-polarizations at θ∣∣ = −4∘ (k∣∣ ~ −0. 3 Å−1) taken before and after magnetization at 80 eV with p-polarized light. All error bars represent standard deviation. The insets show the schematics of multi-magnetic domains and a single-magnetic ___domain. c Calculated band dispersion with EF shifted upward by 70 meV (left) and spin-polarization map along the Γ–K–X line (right). d Spin-resolved ARPES images of the majority (left) and minority (right) spin states. e Spin-resolved EDCs taken from θ∣∣ = 0∘ to 20∘ (Γ–K–X). The background signal of the secondary electrons was subtracted. Inverted triangles indicate the peak position of the minority spin-polarized flat band.
