Journal ArticleDOI
Microwave determination of the quasiparticle scattering time in YBa2Cu3O6.95.
D. A. Bonn,Ruixing Liang,T. M. Riseman,D. J. Baar,D. C. Morgan,Kuan Zhang,Pinder Dosanjh,Tim Duty,A. MacFarlane,G. D. Morris,J. H. Brewer,Walter Hardy,Catherine Kallin,A. J. Berlinsky +13 more
TL;DR: Microwave surface resistance measurements on two very-high-quality YBa2Cu3O6.95 crystals are reported, inferring that λ2(0)/λ2(T) is well approximated by the simple function 1-t2, and that the low-temperature data are incompatible with the existence of an s-wave, BCS-like gap.
Journal ArticleDOI
New muon-spin-rotation measurement of the temperature dependence of the magnetic penetration depth in YBa 2 Cu 3 O 6.95
J. E. Sonier,Robert F. Kiefl,Jess H. Brewer,D. A. Bonn,J. F. Carolan,Kim H. Chow,Pinder Dosanjh,Walter Hardy,Ruixing Liang,W. A. MacFarlane,P. Mendels,G. D. Morris,T. M. Riseman,J. W. Schneider +13 more
TL;DR: In this paper, the a-b magnetic penetration depth in the vortex state of high quality single crystals was measured in the presence of a strong linear temperature dependence below 50 K which weakens with increasing magnetic field.
Journal ArticleDOI
Local magnetic properties of a monolayer of Mn12 single molecule magnets.

TL;DR: The magnetic properties of a monolayer of Mn12 single molecule magnets grafted onto a silicon (Si) substrate have been investigated using depth-controlled beta-detected nuclear magnetic resonance to probe the local static magnetic field distribution.
Journal ArticleDOI
Muon-spin-rotation study of the effect of Zn substitution on magnetism in YBa2Cu3Ox.

TL;DR: The magnetic properties of YBa2(Cu0.96Zn0.04)3Ox were studied in detail by means of muon spin rotation and relaxation for 6.0≤x≤6.0 and a disordered magnetic state was found to persist between x=6.4 and x≃6.7 (metallic transition), in contrast with pure Y Ba2Cu3Ox.
Journal ArticleDOI
Muonium Formation via Electron Transport in Silicon
Vyacheslav G. Storchak,S. F. J. Cox,Stephen P. Cottrell,J. H. Brewer,G. D. Morris,Donald J. Arseneau,Bassam Hitti +6 more
TL;DR: In this paper, the spin rotation of neutral muonium centers was measured in n-type silicon from 10 to 310k in electric fields up to 5kV/cm, and the spatial distribution of the excess electrons created in the ionization track was shown to be anisotropic with respect to the muon.
