abstract = {Fermi surfaces of transition metals, which describe all
thermodynamical and transport quantities of solids, often
fail to be modeled by one-electron mean-field theory due to
strong correlations among the valence electrons. In
addition, relativistic spin–orbit coupling pronounced in
heavier elements lifts the degeneracy of the energy bands
and further modifies the Fermi surface. Palladium and
rhodium, two 4d metals attributed to show significant
spin–orbit coupling and electron correlations, are ideal
for a systematic and fundamental study of the two
fundamental physical phenomena and their interplay in the
electronic structure. In this study, we explored the Fermi
surface of the 4d noble metals palladium and rhodium
obtained via high-resolution constant initial state momentum
microscopy. The complete 3D-Fermi surfaces of palladium and
rhodium were tomographically mapped using soft X-ray photon
energies from 34 eV up to 660 eV. To fully capture the
orbital angular momentum of states across the Fermi surface,
the Fermi surface tomography was performed using p- and s-
polarized light. Applicability and limitations of the
nearly-free electron final state model in photoemission are
discussed using a complex band structure model supported by
experimental evidence. The significance of spin–orbit
coupling and electron correlations across the Fermi surfaces
will be discussed within the context of the photoemission
results. State-of-the-art fully relativistic
Korringa–Kohn–Rostoker (KKR) calculations within the
one-step model of photoemission are used to support the
experimental results.},
