LDA + U calculations for 4d impurities in Rb - ScienceDirect

Witryna1 paź 2008 · A linear correlation between the out of the core electrons Ne of the impurity and electron density on the iron nucleus was found with the slope −0.0038(7)a.u.−3at.%−1 for all d impurities ... WitrynaWe present detailed calculations of the electronic structure and the hyperfine fields of 3d and 4d impurities in nickel. The calculations are based on the local-density approximation of density-functional theory and the Korringa-Kohn-Rostoker Green's-function method for impurity calculations. Witryna25 lip 2005 · The calculations were performing by adopting two sizes of clusters to represent the bcc matrix of iron where the 4d impurities are embedded. A small cluster of 15 atoms, including two shells of neighbors, and a larger cluster of 57 atoms, with five shells of neighbors around the central atom, representative of bulk. エンコーダー モーター 回転
