Abstract

We report high-resolution angle-resolved photoemission spectroscopy of LaRh₃B₂, which is a nonmagnetic reference compound of RRh₃B₂ (R: rare-earth metals). We found two hole-like Fermi surfaces (FSs) and two electron-like FSs centered at Γ(A) and K(H) points, respectively. The estimated volume of FSs at Γ(A) point shows a good agreement with the LDA band calculation, while the band dispersion and the topology of FSs at K(H) point show a remarkable disagreement.
