Experimental band structure compared with the simulated energy dispersion curves and the theoretical band structure calculations: (a–c) shows the experimental band structure at the 100 K (PM phase), 50 K (near AFM phase) and 20 K (FM phase) respectively, compared with the simulated energy dispersion curves in the k a direction. The simulation has been carried out with the equation described in the text. Solid and dotted lines represents hole-like and electron-like bands, respectively. E+ (red line) and E− (black line) corresponds to the bands simulated with spin index +1 and −1, respectively. (d,e) shows the experimental band structure at 20 K (FM phase) and 100 K (PM phase) compared with the simulated energy dispersion curves in the k c direction. The theoretical band structure of the Pr terminated [010] surface with the anti-parallel spin orientation showing the bands (f) without considering the spin-orbit coupling and (g) with the spin-orbit coupling in the k a direction. (h) shows zoomed region of the theoretical band structure calculation along the k a (\(\bar{X}^{\prime} \)-\(\bar{{\rm{\Gamma }}}\)-\(\bar{X}\)) direction and (i) shows the zoomed region of theoretical band structure calculation along the k c (\(\bar{Z}^{\prime} \)-\(\bar{{\rm{\Gamma }}}\)-\(\bar{Z}\)) direction.
