Spectroscopic evidence of Kondo-induced quasi-quartet in CeRhAs
Denise S. Christovam, Miguel Ferreira-Carvalho, Andrea Marino +13
CeRhAs is a new multiphase superconductor with strong suggestions for an additional itinerant multipolar ordered phase. The modeling of the low temperature properties of th…
Electronic structure investigation of GdNi using X-ray absorption, magnetic circular dichroism and hard x-ray photoemission spectroscopy
C. W. Chuang, H. J. Lin, F. M. F. de Groot +8
GdNi is a ferrimagnetic material with a Curie temperature Tc = 69 K which exhibits a large magnetocaloric effect, making it useful for magnetic refrigerator applications. We invest…
Spin-orbit coupling and crystal-field distortions for a low-spin state in BaCoO
Y. Y. Chin, Z. Hu, H. -J. Lin +13
We have studied the electronic structure of BaCoO using soft x-ray absorption spectroscopy at the Co- and O- edges, magnetic circular dichroism at the Co-…
Intermediate valence in single crystalline YbSiAl
W. J. Gannon, K. Chen, M. Sundermann +8
YbSiAl may be a prototype for exploring different aspects of the Shastry-Sutherland lattice, formed by planes of orthogonally coupled Yb ions. Measurements of the magnetic…

The occupancy of the 4f^n contributions in the Kondo semiconductors CeM2Al10(M = Ru, Os and Fe) has been quantitatively determined by means of bulk-sensitive hard x-ray photoelectr…
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…
