Systematic manipulation of the surface conductivity of SmB
M. Victoria Ale Crivillero, M. König, J. C. Souza +5
We show that the resistivity plateau of SmB at low temperature, typically taken as a hallmark of its conducting surface state, can systematically be influenced by different sur…
Revisiting the Possible 4f7 5d1 Ground State of Gd Impurities in SmB6 by Electron Spin Resonance
J. C. Souza, P. F. S. Rosa, U. Burkhardt +5
The search for topological states in strongly correlated electron systems has renewed the interest in the Kondo insulator SmB6. One of the most intriguing previous results was an a…
Evolution of ground state wave function in CeCoIn upon Cd or Sn doping
K. Chen, F. Strigari, M. Sundermann +13
We present linear polarization-dependent soft x-ray absorption spectroscopy data at the Ce edges of Cd and Sn doped CeCoIn. The 4 ground state wave functions have…
Bulk and surface electronic properties of SmB6: a hard x-ray photoelectron spectroscopy study
Y. Utsumi, D. Kasinathan, K-T. Ko +10
We have carried out bulk-sensitive hard x-ray photoelectron spectroscopy (HAXPES) measurements on in-situ cleaved and ex-situ polished SmB6 single crystals. Using the multiplet-str…
Valence state of Sm in single crystalline EuO thin films
A. Reisner, D. Kasinathan, S. Wirth +2
Samarium has two stable valence states, 2+ and 3+, which coexist in many compounds forming spatially homogeneous intermediate valence states. We study the valence state of samarium…
Direct observation of electron doping in La0.7Ce0.3MnO3 using x-ray absorption spectroscopy
C. Mitra, Z. Hu, P. Raychaudhuri +6
We report on a X-ray absorption spectroscopic (XAS) study on a thin film of La0.7Ce0.3MnO3, a manganite which was previously only speculated to be an electron doped system. The mea…
