Journal ArticleDOI
Coexistence of static magnetism and superconductivity in SmFeAsO(1-x)F(x) as revealed by muon spin rotation.

TL;DR: A muon spin rotation study on SmFeAsO(1-x)F(x), with x=0-0.30 that shows that, as in the cuprates, static magnetism persists well into the superconducting regime, suggests that the proximity to magnetic order and associated soft magnetic fluctuations, rather than strong electronic correlations in the vicinity of a Mott-Hubbard transition, may be the key ingredients of high-Tc superconductors.
Journal ArticleDOI
Structure and properties of tris[bis(ethylenedithio)tetrathiafulvalenium]tetrachlorocopper(II) hydrate, (BEDT-TTF)3CuCl4.H2O: first evidence for coexistence of localized and conduction electrons in a metallic charge-transfer salt
Peter Day,Mohamedally Kurmoo,Talal Mallah,I. R. Marsden,Richard H. Friend,F. L. Pratt,William Hayes,Daniel Chasseau,J. Gaultier +8 more
TL;DR: In this article, the synthesis and physical characterization of a complex of BEDT-TTF [bis(ethylenedithio)tetrathiafulvalenium] with Cu II Cl 4 2- are reported.
Journal ArticleDOI
Coexistence of static magnetism and superconductivity in SmFeAsO1-xFx as revealed by muon spin rotation
Alan J. Drew,Ch. Niedermayer,P. J. Baker,F. L. Pratt,S. J. Blundell,Tom Lancaster,Ronghua Liu,Gang Wu,Xianhui Chen,Isao Watanabe,Vivek Kumar Malik,Adam Dubroka,M. Roessle,Kyung Wan Kim,C. Baines,Christian Bernhard +15 more
TL;DR: In this article, a muon spin rotation study on SmFeAsO1-xFx (x=0-0.30) was presented, which showed that static magnetism persists well into the superconducting regime.
Journal ArticleDOI
Magnetotransport studies of the organic superconductor kappa -(BEDT-TTF)2Cu(NCS)2 under pressure: the relationship between carrier effective mass and critical temperature
J. Caulfield,W. Lubczynski,F. L. Pratt,John Singleton,D Y K Ko,William Hayes,M. Kurmoo,Peter Day +7 more
TL;DR: In this article, a simplified model of the band structure of kappa -(BEDT-TTF)2Cu(NCS)2 has been used to derive the bare band masses of the electrons from optical data.
Journal ArticleDOI
Coexistence of Magnetic Fluctuations and Superconductivity in the Pnictide High Temperature Superconductor SmFeAsO 1 x F x Measured by Muon Spin Rotation
Alan J. Drew,F. L. Pratt,Tom Lancaster,Stephen J. Blundell,Peter J. Baker,Ronghua Liu,Gang Wu,Xianhui Chen,Isao Watanabe,Vivek Kumar Malik,Adam Dubroka,Kyung Wan Kim,Matthias Rössle,Christian Bernhard +13 more
TL;DR: An estimate of the in-plane penetration depth lambda ab(0)=190(5) nm was obtained, which confirms that the pnictide superconductors obey an Uemura-style relationship between Tc andlambda ab( 0);(-2).
