“…These values should be compared to the experimental lattice parameter which is equal to 9.75 a.u. 70 , showing again that the AM05+HI approach results in the best agreement with experiment. For γ-Ce we have also calculated the bulk modulus to investigate if the lack of the well-screened 4f feature in the spectrum leads to a deficiency in more sensitive ground state properties than the lattice constant.…”

We present calculated spectral properties and lattice parameters for cerium pnictides (CeN, CeP, CeAs, CeSb, CeBi) and γ-Ce, within the LDA/GGA+DMFT (local density approximation/generalized gradient approximation + dynamical mean field theory) approach. The effective impurity model arising in the DMFT is solved by using the spin-polarized T-matrix fluctuationexchange (SPTF) solver for CeN compound, and the Hubbard I (HI) solver for CeP, CeAs, CeSb, and CeBi. For all the addressed compounds the calculated spectral properties are in reasonable agreement with measured photoelectron spectra at high binding energies. At low binding energies the HI approximation does not manage to capture the Kondo-like peak observed for several of the Ce-pnictides. Nevertheless, the calculated lattice constants are in a good agreement with available experimental data, showing that the such a peak does not play a major role on the bonding properties. Furthermore, the HI calculations are compared to a simpler treatment of the Ce 4f electron as core-like in LDA/GGA for CeP, CeAs, CeSb, and CeBi, and the two approaches are found to give similar results.

“…The lattice parameters are a=3.664(3) Å, c=2.970(3) Å (in niobium c=2.949(3) Å) implying a small compression within the hexagonal planes (0.5%) and a small expansion between the planes (0.2%) in comparison with the bulk -phase [16]. Unlike the bulk phase the epitaxial -phase (e--Се) does not transform to -Се.…”
