Abstract Die ternären Verbindungen vom NaZn 13 ‐Typ wurden bei der röntgenographischen Strukturuntersuchung Systeme Lanthan‐Nickel‐Silicium (∼ LaNi 10,5 Si 2,5 , a = 11,27 bis 11,35 Å) und Lanthan‐Eisen‐Silicium LaFe 11,5 1,5 10,51–10,52 gefunden; diese kann man als Glieder isoelektronischen Reihen, die mit LaZn bzw. LaCo beginnen, ansehen. Phasen von demselben Typ in den Systemen Lanthan‐Kobalt‐Silicium Lanthan‐Kobalt‐Aluminium sind ‐Mischkristalle. bilden sich auch Cer‐Kobalt‐Silicium...
Abstract Die Existenz der ternären Verbindungen R 3 Ni 6 Si 2 (R = Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tu, Yb, Lu) mit Überstruktur des Ca Ag 8 ‐Typs wurde röntgenographisch festgestellt. Gitterkonstanten sind in Tab. zusammengefaßt. Atome Ce 5 ‐Struktur besetzen folgende Lagen (Raumgruppe Im3mO ): 12 (e) x 0 0,280, 24 (h) 0,670, (c) 1/4 1/4.
The title compounds, dialuminium triiron trisilicide and tetrasilicide, crystallize with new structure types. coordination polyhedra in Fe3Al2Si3 derive from icosahedra, those Fe3Al2Si4 hexagonal cuboctahedra.
Abstract The experimental results of the components substitution effect on crystal structure, electronic transport properties, and Eu effective valence in solid solutions based EuCu 2 Si EuPd ternary compounds are presented. It is shown, that when reaches critical value v = 2.1, corresponding to degeneration 4f 7 6 configurations, condition concentrated Kondo system an essential perturbation band electron spectrum near Fermi level occur.
Rietveld analysis was performed for the intermetallics Yb3Co4.3Sn12.7 and Yb3Co4Ge13 crystallizing with closely related structure types, Yb3Rh4Sn13 Yb3Co4Ge13. Below Tc = 3.4 K crosses over into a type-II superconducting ground state Hc2(0)~2.5 T. stays in normal down to 300 mK. The γ value of 2.3(2) mJ gat-1 K-2 Debye temperature ΘD 207(5) deduced from specific heat as well correspond that elementary Sn, thus indicating conventional BCS superconductivity. Hydrostatic pressure applied...
