Fig. 1: Electronic structure of paramagnetic state and two magnetic domains of the antiferromagnetic ground state near\(\bar{\Gamma }\).
From: Unconventional band splitting of CeSb in the devil’s staircase transition
a Arrangement of magnetic moments of the type- IA antiferromagnetic structure, illustrating two possible magnetic domains: the c-domain and the ab-domain. b Brillouin zones of the paramagnetic phase and the type-IA antiferromagnetic phase. c ARPES intensity along \(\bar{\Gamma }{\bar{\rm X}}_{{{\rm{PM}}}}\) in the paramagnetic phase. The EDC obtained along the red dashed line is plotted on the right side, revealing a distinct band gap. d Calculated band structure along \(\bar{\Gamma }{\bar{\rm X}}_{{{\rm{PM}}}}\) in the paramagnetic phase. e The Fermi surface map of the c-domain near the \(\bar{\Gamma }\) point. f The Fermi surface map of the ab-domain near the \(\bar{\Gamma }\) point. g, h ARPES intensity plots along \(\bar{\Gamma }{\bar{\rm X}}_{{{\rm{PM}}}}\) of cut 1 in (e) and cut 2 in (f), respectively.
