Variation of Pressure-Induced Valence Transition with Approximation Degree in Yb-Based Quasicrystalline Approximants

Keiichiro Imura, Yuki Yoneyama, Hideyuki Ando +6

We have synthesized new Tsai-type Yb-based intermediate-valence approximant crystals (ACs) with different degree of approximation to quasicrystal, Zn--Au--Yb 1/1 and 2/1 AC, and st…

Unified understanding of the valence transition in the rare-earth monochalcogenides under pressure

Ignace Jarrige, Hitoshi Yamaoka, Jean-Pascal Rueff +10

Valence instability is a key ingredient of the unusual properties of f electron materials, yet a clear understanding is lacking as it involves a complex interplay between f electro…
