Crystal structure of the compounds Ce3Pd20Ge6 and Ce3Pd20Si6

Crystal Growth and Stoichiometry of Strongly Correlated Intermetallic Cerium Compounds

“…1). There is only a single peak both on the heating and on the cooling curve, indicating congruent melting as previously reported [Gribanov et al (1994)]. A closer inspection of the shape of the melting peak (Fig.…”

“…[Goto et al (2009) ;Strydom et al (2006); Takeda et al (1995)]) demonstrates this delicate dependence. Also the non-negligible difference in the reported unit cell constants [Gribanov et al (1994), Takeda et al (1995)] needs a clarification. This has motivated us to undertake a systematic investigation of the relation between crystal growth techniques/conditions, sample quality, and the resulting physical properties down to dilution refrigerator temperatures.…”

“…Ce 3 Pd 20 Si 6 crystallizes in a cubic Cr 23 C 6 -type structure with the space group Fm3m [Gribanov et al (1994)]. The cubic cell with a= 12.161 Å [Gribanov et al (1994)]; 12.280 Å [Takeda et al (1995)] contains 116 atoms. The Ce atoms occupy two distinct sites of cubic point symmetry.…”

Synthesis and physical properties of a new caged compound Ce3Pd20As6 of the C6Cr23-type structure

“…The simulated pattern in Fig 6 patterns [18]. The sample #1 using As powder as the starting material shows noticeable impurity peaks (see triangles).…”

“…Ce-Pd-X (X=P and As) compounds that the phases are stabilized by the inevitable disorder, which is contrasted with negligible atomic disorder [18] in The data of ρ(T) of Ce 3 Pd 20 As 6 #4 (metallic luster) indicates a metallic behavior (see Fig. 4(b)).…”
