Doping Effects on the Electronic Structure of an Anisotropic Kondo Semiconductor CeOsAl: An Optical Study with Re and Ir Substitution
Shin-ichi Kimura, Hitoshi Takao, Jo Kawabata +2
An anisotropic Kondo semiconductor CeOsAl exhibits an unusual antiferromagnetic order at rather high transition temperature of 28.5 K. Two possible origins of the…
Inelastic neutron scattering investigations of an anisotropic hybridization gap in the Kondo insulators: CeT2Al10 (T=Fe, Ru and Os)
D. T. Adroja, Y. Muro, T. Takabatake +4
The recent discovery of topological Kondo insulating behaviour in strongly correlated electron systems has generated considerable interest in Kondo insulators both experimentally a…
Quadrupole-Driven Non-Fermi Liquid and Magnetic-Field Induced Heavy Fermion States in a Non-Kramers Doublet System
T. Onimaru, K. Izawa, K. T. Matsumoto +9
Orbital degrees of freedom in condensed matters could play important roles in forming a variety of exotic electronic states by interacting with conduction electrons. In 4f electron…
Giant isotropic Nernst effect in an anisotropic Kondo semimetal
Ulrike Stockert, Peije Sun, Niels Oeschler +4
The "failed Kondo insulator" CeNiSn has long been suspected to be a nodal metal, with a node in the hybridization matrix elements. Here we carry out a series of Nernst effect exper…
Quantitative study of the f occupation in CeMIn5 and other cerium compounds with hard x-rays
M. Sundermann, F. Strigari, T. Willers +19
We present bulk-sensitive hard x-ray photoelectron spectroscopy (HAXPES) data of the Ce3d core levels and lifetime-reduced L edge x-ray absorption spectroscopy (XAS) in the partial…
