“…5 Matsumoto et al related the shape of the Fermi surfaces to helical spin ordering then reported the first self-consistent KKR results for α = 1.0 and 0.67, placing the occupied 4f bands near those from experiment. 6,7 . Matsumoto et al then reported self-consistent paramagnetic band structure using the Xα-KKR method.…”

We have calculated the electronic structure of Eu for the bcc, hcp, and fcc crystal structures for volumes near equilibrium up to a calculated 90 GPa pressure using the augmented-plane wave method in the local-density approximation. The frozen-core approximation was used with a semi-empirical shift of the f-states energies in the radial Schrödinger equation to move the occupied 4f valence states below the Γ 1 energy and into the core. This shift of the highly localized f-states yields the correct europium phase ordering with lattice parameters and bulk moduli in good agreement with experimental data. The calculated superconductivity properties under pressure for the bcc and hcp structures are also found to agree with and follow a T c trend similar to recent measurement by Debessai et al.1
