Heat capacity measurements on FeAs-based compounds: a thermodynamic probe of electronic and magnetic states
P. J. Baker, S. R. Giblin, F. L. Pratt +7
We report heat capacity measurements of the pnictide materials SmFeAsOF, NdFeAsO, LaFeAsOF and LiFeAs. For SmFeAsOF, with x close to 0.1, we use…
Enhancement of Superfluid Stiffness, Suppression of Superconducting T_c and Field-induced Magnetism in the Pnictide Superconductor LiFeAs
F. L. Pratt, P. J. Baker, S. J. Blundell +6
Transverse-field muon-spin rotation measurements performed on two samples of LiFeAs demonstrate that the superfluid stiffness of the superconducting condensate in relation to its s…
Structure, antiferromagnetism and superconductivity of the layered iron arsenide NaFeAs
Dinah R. Parker, Michael J. Pitcher, Peter J Baker +4
A new layered iron arsenide NaFeAs isostructural with the superconducting lithium analogue, displays evidence for the coexistence of superconductivity and magnetic ordering.
Determination of characteristic muon precession and relaxation signals in FeAs and FeAs2, possible impurity phases in pnictide superconductors
P. J. Baker, H. J. Lewtas, S. J. Blundell +5
We report muon-spin relaxation measurements of highly homogeneous samples of FeAs and FeAs2, both previously found as impurity phases in some samples of recently synthesized pnicti…
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…
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…
