The gradual destruction of magnetism in the superconducting family NaFe(1-x)CoxAs
J. D. Wright, T. Lancaster, I. Franke +10
The interplay and coexistence of superconducting, magnetic and structural order parameters in NaFe{1-x}Co{x}As has been studied using SQUID magnetometry, muon-spin rotation and syn…
Spin fluctuations in LiFeAs observed by neutron scattering
A. E. Taylor, M. J. Pitcher, R. A. Ewings +3
We report neutron inelastic scattering measurements on the stoichiometric iron-based superconductor LiFeAs. We find evidence for (i) magnetic scattering consistent with strong anti…
Control via electron count of the competition between magnetism and superconductivity in cobalt and nickel doped NaFeAs
Dinah R. Parker, Matthew J. P. Smith, Tom Lancaster +7
Using a combination of neutron, muon and synchrotron techniques we show how the magnetic state in NaFeAs can be tuned into superconductivity by replacing Fe by either Co or Ni. Ele…
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.
