Kondo scenario of the γ-α phase transition in single crystalline Cerium thin films
Xie-Gang Zhu, Yu Liu, Ya-Wen Zhao +17
The physical mechanism driving the - phase transition of face-centre-cubic (fcc) cerium (Ce) remains controversial until now. In this work, high quality single crystalline fc…
Direct observation of heavy quasiparticles in the Kondo lattice CeIn3
Y. Zhang, W. Feng, X. Lou +15
The electronic structure of the Kondo lattice CeIn3 has been studied by on-resonant angle-resolved photoemission spectroscopy and scanning tunneling microscopy/spectroscopy. A weak…
Direct measurement of the localized-itinerant transition, hybridization and antiferromagnetic transition of 5f electrons
D. H. Xie, M. L. Li, W. Zhang +12
In heavy-fermion compounds, f electrons show both itinerant and localized behaviour depending on the external conditions, and the hybridization between localized f electrons and it…
Three-dimensional bulk electronic structure of the Kondo lattice CeIn3 revealed by photoemission
Yun Zhang, Haiyan Lu, Xiegang Zhu +10
We show the three-dimensional electronic structure of the Kondo lattice CeIn3 using soft x-ray angle resolved photoemission spectroscopy in the paramagnetic state. For the first ti…
Observation of Dirac Cone Band Dispersion in FeSe Thin Films by Photoemission Spectroscopy
S. Y. Tan, Y. Fang, D. H. Xie +10
The electronic structure of FeSe thin films grown on SrTiO3 substrate is studied by angle-resolved photoemission spectroscopy (ARPES). We reveal the existence of Dirac cone band di…
