Abstract

The electronic structure of ThPd $_{2}$ Al $_{3}$ , which is isostructural to the heavy fermion superconductor UPd $_{2}$ Al $_{3}$ , was investigated by photoelectron spectroscopy. The band structure and Fermi surfaces of ThPd $_{2}$ Al $_{3}$ were obtained by angle-resolved photoelectron spectroscopy (ARPES), and the results were well-explained by the band-structure calculation based on the local density approximation. The comparison between the ARPES spectra and the band-structure calculation suggests that the Fermi surface of ThPd $_{2}$ Al $_{3}$ mainly consists of the Al $3 p$ and Th $6 d$ states with a minor contribution from the Pd $4 d$ states. The comparison of the band structures between ThPd $_{2}$ Al $_{3}$ and UPd $_{2}$ Al $_{3}$ argues that the U $5 f$ states form Fermi surfaces in UPd $_{2}$ Al $_{3}$ through hybridization with the Al $3 p$ state in the Al layer, suggesting that the Fermi surface of UPd $_{2}$ Al $_{3}$ has a strong three-dimensional nature.
