WitrynaThe concentration of Yb 3+ ions increases monotonically with the ytterbium content, while a significant fraction of ytterbium ions remains in a nonmagnetic Yb 2+ state. This is explained within the electronic band-structure model, assuming the ytterbium-derived donor states form an impurity band in the vicinity of the valence-band top. WitrynaThe binary systems Ca−Sn, Ba−Sn, Eu−Sn, Yb−Sn, Sr−Pb, Ba−Pb, and Eu−Pb do not contain Cr5B3-like A5Tt3 phases when care is taken to exclude hydrogen from the reactions (Tt = tetrel, Si−Pb).
