Caption
a) Fermi surface of LaRh₃B₂ measured by synchrotron-radiation ARPES measurements. (b) Energy-band dispersions measured along momentum cuts 1 and 2 indicated in (a). Along cut 1, a convex band is observed, as indicated by the red curve. Along the orthogonal cut 2, a concave dispersion with a slightly flattened top is observed, revealing the presence of a saddle-point structure. (c) Schematic illustration of the energy-band dispersion in (b) around the saddle point at the M point.
