摘要
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 Gamma(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. (c) 2006 Elsevier B.V. All rights reserved.
