Abstract

We performed high-resolution angle-resolved photoemission spectroscopy (ARPES) on quasi-two-dimensional rare-earth intermetallic compounds LaAgSb2 and CeAgSb2. In CeAgSb2, we found highly dispersive bands in the vicinity of the Fermi level, showing a hole-like dispersion centered at the Γ(Z) point in the Brillouin zone. These bands produce small hole pockets at the zone center, in good agreement with the band calculation of LaAgSb2.
