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…
Interpretation of the in-plane infrared response of the high-Tc cuprate superconductors involving spin fluctuations revisited
Petr Casek, Christian Bernhard, Josef Humlicek +1
The in-plane infrared response of the high-Tc cuprate superconductors was studied using the spin-fermion model, where charged quasiparticles of the copper-oxygen planes are coupled…
Magnetic Proximity Effect in Perovskite Superconductor/Ferromagnet Multilayers
J. Stahn, J. Chakhalian, C. Niedermayer +8
superconducting/ferromagnetic (SC/FM) multilayers have been studied by neutron reflectometry. Evidence for a characteristic difference…
