Coexistence of static magnetism and superconductivity in SmFeAsO1-xFx as revealed by muon spin rotation
A. J. Drew, Ch. Niedermayer, P. J. Baker +13
The recent observation of superconductivity with critical temperatures up to 55 K in the FeAs based pnictide compounds marks the first discovery of a non copper-oxide based layered…
Superconducting energy gap and c-axis plasma frequency of (Nd,Sm)O0.82F0.18FeAs superconductors from infrared ellipsometry
A. Dubroka, K. W. Kim, M. Roessle +5
We present ellipsometric measurements of the far-infrared dielectric response of polycrystalline samples of the new pnictide superconductor RO0.82F0.18FeAs (R=Nd and Sm). We find e…
Coexistence of magnetic fluctuations and superconductivity in the pnictide high temperature superconductor SmFeAsOF measured by muon spin rotation
A. J. Drew, F. L. Pratt, T. Lancaster +11
Muon-spin rotation experiments were performed on the pnictide high temperature superconductor SmFeAsOF with x=0.18 and 0.3. We observed an unusual enhancement of slow…
Raman and infrared studies of La_1-ySr_yMn_1-xM_xO_3 (M=Cr, Co, Cu, Zn, Sc or Ga): Oxygen disorder and local vibrational modes
A. Dubroka, J. Humlicek, M. V. Abrashev +3
We present results of our study of polarized Raman scattering and infrared reflectivity of rhombohedral ceramic La_1-ySr_yMn_1-xM_xO_3 manganites in the temperature range between 7…
