- YbCoGe is identified as the first material exhibiting a Remeika phase with a specific modulated crystal structure characterized by a 3 + 3 symmetry.
- Increasing the proportion of Yb in YbCoGe eliminates satellite reflections and stabilizes a disordered primitive cubic structure.
- This compound functions as a metal with hole-like charge carriers, where Yb ions exhibit a temperature-dependent intermediate valence state that fluctuates between +2.60 and +2.66 from 85 to 293 K, studied using various spectroscopy and measurement techniques.
A series of new ternary isostructural RCoC (R = Y, Gd, Tb) carbides was synthesized by annealing of arc-melted stoichiometric samples. The crystal structure of TbCoC [space group P2/m, Pearson symbol mP18, a = 12.754(2) Å, b = 3.
