Probing the localized to itinerant behavior of the 4f electron in CeIn3-xSnx by Gd3+ electron spin resonance
E. M. Bittar, C. Adriano, C. Giles +3
The CeIn3-xSnx cubic heavy fermion system presents an antiferromagnetic transition at T_N = 10 K, for x = 0, that decreases continuously down to 0 K upon Sn substitution at a criti…
Electron spin resonance study of the LaIn3-xSnx superconducting system
E. M. Bittar, C. Adriano, C. Giles +3
The LaIn3-xSnx alloy system is composed of superconducting Pauli paramagnets. For LaIn3 the superconducting critical temperature T_c is approximately 0.7 K and it shows an oscillat…
Co-substitution effects on the Fe-valence in the BaFe2As2 superconducting compound: A study of hard x-ray absorption spectroscopy
E. M. Bittar, C. Adriano, T. M. Garitezi +6
The Fe K X-ray absorption near edge structure (XANES) of BaFe2-xCoxAs2 superconductors was investigated. No appreciable alteration in shape or energy position of this edge was obse…
Pressure and chemical substitution effects in the local atomic structure of BaFe2As2
E. Granado, L. Mendonca-Ferreira, F. Garcia +10
The effects of K and Co substitutions and quasi-hydrostatic applied pressure (P<9 GPa) in the local atomic structure of BaFe2As2, Ba(Fe{0.937}Co{0.063})2As2 and Ba{0.85}K{0.15}Fe2A…
