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…
Doping induced magnetic clusters and Co spin state transition in Na_xCoO_2 with 0.78<x<.97
C. Bernhard, Ch. Niedermayer, A. Drew +7
By muon spin rotation we investigated the magnetic properties of a series of highly Na doped NaxCoO2 single crystals with 0.78(1)<x<0.97(1). Our data provide evidence for an intrin…
Square vortex lattice at anomalously low magnetic fields in electron-doped NdCeCuO
R. Gilardi, J. Mesot, S. P. Brown +7
We report here on the first direct observations of the vortex lattice in the bulk of electron-doped NdCeCuO single crystals. Using small angle neutron scatt…
