Abstract

The correlation between the 4f -conduction electron (c-f) hybridization and the transition temperature T-0 into the unconventional antiferromagnetically (AFM) ordered state in Ce(Ru1-xFex)(2)Al-10 has been investigated. The impact of pressure on the crystal structure and the electronic structure has been measured using x-ray diffraction and resonant x-ray emission spectroscopy at the Ce L-3 absorption edge in a diamond anvil cell. Our results show that the lattice spacings imply some correlation with the disappearance of T-0. Analyses of the measured valence states, however, show only a weak correlation with the corresponding critical disappearance of the AFM order within experimental errors. Our results may be explained by a scenario based on the Kondo-Heisenberg model beyond the conventional Doniach phase diagram.
