Journal ArticleDOI
Magnetic Coulomb phase in the spin ice Ho2Ti2O7.
Tom Fennell,Pascale P. Deen,Andrew Wildes,K. Schmalzl,D. Prabhakaran,Andrew T. Boothroyd,R. J. Aldus,Desmond F. McMorrow,Steven T. Bramwell +8 more
TL;DR: P polarized neutron scattering is used to show that the spin-ice material Ho2Ti2O7 exhibits an almost perfect Coulomb phase, which proves the existence of such phases in magnetic materials and strongly supports the magnetic monopole theory of spin ice.
Journal ArticleDOI
A ferroelectric-like structural transition in a metal
Youguo Shi,Yanfeng Guo,Yanfeng Guo,Xia Wang,A. J. Princep,Dmitry D. Khalyavin,Pascal Manuel,Yuichi Michiue,Akira Sato,Kenji Tsuda,Shan Yu,Masao Arai,Yuichi Shirako,Masaki Akaogi,Nanlin Wang,Kazunari Yamaura,Andrew T. Boothroyd +16 more
TL;DR: A centrosymetric to non-centrosymmetric (R3c) transition in metallic LiOsO3 that is structurally equivalent to the ferroelectric transition of LiNbO3 is reported, which establishes a new class of materials whose properties may differ from those of normal metals.
Journal ArticleDOI
Structure and superconductivity of LiFeAs.
Michael J. Pitcher,Dinah R. Parker,Paul Adamson,Sebastian J. C. Herkelrath,Andrew T. Boothroyd,Richard M. Ibberson,Michela Brunelli,Simon J. Clarke +7 more
TL;DR: In this paper, LiFeAs−anionic layers with the anti-PbO structure type occur in at least three different structure types and with a wide range of As-Fe-As bond angles.
Journal ArticleDOI
Structure and superconductivity of LiFeAs
Michael J. Pitcher,Dinah R. Parker,Paul Adamson,Sebastian J. C. Herkelrath,Andrew T. Boothroyd,Simon J. Clarke +5 more
TL;DR: In this paper, the superconductivity of LiFeAs-anti-PbO-type anionic layers was demonstrated for a wide range of As-Fe-As-As bond angles.
