Short-range correlations in binary alloys: Spin model approach to AgPd
I. Vilja, K. Kokko
Short-range correlations in Ag-Pd alloys are investigated by analyzing the {\em ab initio} total energy of fcc based random AgPd. Since the information on the atomic in…
Initial oxidation of Fe-Al and Fe-Cr-Al alloys: Cr as an alumina booster
Markku Heinonen, Kalevi Kokko, Marko Punkkinen +3
The boosting effect of Cr on the growth of the protective alumina scale on Fe-Al alloys is investigated by x-ray photoelectron spectroscopy. Using low oxygen pressure the surface c…
Proving the Perdew-Burke-Ernzerhof density functional designed for metallic bulk and surface systems
M. Ropo, K. Kokko, L. Vitos
We test the accuracy of the revised Perdew-Burke-Ernzerhof exchange-correlation density functional (PBEsol) for metallic bulk and surface systems. It is shown that, on average, PBE…
Resonant inelastic x-ray scattering (RIXS) spectra of magnesium diboride
K. Kokko, V. Kulmala, J. A. Leiro +1
Using the tight-binding linear muffin-tin orbitals method, the soft x-ray fluorescence K-emission spectra of boron in MgB_2, excited close to the absorption edge, are estimated. In…
