Journal ArticleDOI
Dirac strings and magnetic monopoles in the spin ice Dy2Ti2O7.
David Jonathan Morris,David Tennant,David Tennant,Santiago Andrés Grigera,Santiago Andrés Grigera,B. Klemke,B. Klemke,Claudio Castelnovo,Roderich Moessner,C. Czternasty,Michael Meissner,Kirrily C. Rule,J.-U. Hoffmann,Klaus Kiefer,S. Gerischer,D. Slobinsky,Robin Perry +16 more
TL;DR: In this article, the authors demonstrated the presence of magnetic monopoles in the spin ice dysprosium titanate (Dy2Ti2O7) by diffuse neutron scattering, which is achieved by applying a symmetry-breaking magnetic field with which they can manipulate the density and orientation of the strings.
Journal ArticleDOI
Magnetic field-tuned quantum criticality in the metallic ruthenate Sr3Ru2O7.
Santiago Andrés Grigera,Santiago Andrés Grigera,Robin Perry,Andrew J. Schofield,May Chiao,Stephen Julian,Gilbert G. Lonzarich,Shinichi Ikeda,Shinichi Ikeda,Yoshiteru Maeno,Andrew J. Millis,Andrew P. Mackenzie,Andrew P. Mackenzie +12 more
TL;DR: It is argued that observations on the itinerant metamagnet Sr3Ru2O7 represent good evidence for a new class of quantum critical point, arising when the critical end point terminating a line of first-order transitions is depressed toward zero temperature.
Journal ArticleDOI
Formation of a Nematic Fluid at High Fields in Sr3Ru2O7
Rodolfo Alberto Borzi,Rodolfo Alberto Borzi,Santiago Andrés Grigera,Santiago Andrés Grigera,J. Farrell,Robin Perry,S. J. Lister,Stephen Lee,David Tennant,Yoshiteru Maeno,Andrew P. Mackenzie +10 more
TL;DR: It is reported that, in the close vicinity of a metamagnetic quantum critical point, high-purity strontium ruthenate Sr3Ru2O7 possesses a large magnetoresistive anisotropy, consistent with the existence of an electronic nematic fluid.
Journal Article
Dirac Strings and Magnetic Monopoles in Spin Ice Dy2Ti2O7
TL;DR: Neutron scattering measurements on two spin-ice compounds show evidence for magnetic monopoles, and it is demonstrated the presence of such strings in the spin ice dysprosium titanate (Dy2Ti2O7).
Journal ArticleDOI
Metamagnetism and Critical Fluctuations in High Quality Single Crystals of the Bilayer Ruthenate Sr3Ru2O7
Robin Perry,L. M. Galvin,Santiago Andrés Grigera,L. Capogna,Andrew J. Schofield,Andrew P. Mackenzie,May Chiao,Stephen Julian,Shinichi Ikeda,Satoru Nakatsuji,Y. Maeno,Christian Pfleiderer +11 more
TL;DR: The results of low temperature transport, specific heat, and magnetization measurements on high quality single crystals of the bilayer perovskite Sr3Ru2O7, which is a close relative of the unconventional superconductor Sr2RuO4, are reported.
