Eu2+ spin dynamics in the filled skutterudites EuM4Sb12 (M = Fe, Ru, Os)
F. A. Garcia, C. Adriano, G. G. Cabrera +5
We report evidence for a close relation between the thermal activation of the rattling motion of the filler guest atoms, and inhomogeneous spin dynamics of the Eu2+ spins. The spin…
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…
The magnetic structures of the anisotropic inter-metallic compounds ErCoGa and TmCoGa
R. D. Johnson, T. Frawley, P. Manuel +5
Two members of the iso-structural RCoGa inter-metallic series, ErCoGa and TmCoGa, have been studied by powder neutron diffraction. Antiferromagnetic orderin…
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…
