Figure 4: Insight into the bulk electronic structure.

Experimental ARPES data of EuRh₂Si₂ recorded using 950 eV photons, which allows to suppress the emission from the surface states and thus to disentangle the bulk electron structure of the system. The dotted frame shows the region where conically shaped Rh bands with their apex close to the Fermi level are coupled with a bunch of ‘horizontal’ bands from the bulk Eu 4f⁶ multiplet.
