Journal ArticleDOI
Charge localization by static and dynamic distortions of the MnO6 octahedra in perovskite manganites.
TL;DR: In this paper, transport and neutron-diffraction data establishing a clear link between static and dynamic distortions of the MnO octahedra and charge mobility in the A-site ionic radius were presented.
Journal ArticleDOI
Ultrasonic-attenuation in upt3
TL;DR: In this article, the ultrasonic absorption in UP${\mathrm{t}}_{3}$ through the superconducting transition was investigated and it was shown that the attenuation varies with low temperature and is inconsistent with the identification of UP${t}_{3]$ as a singlet superconductor, where the gap vanishes along a line on the Fermi surface.
Journal ArticleDOI
Aluminum Substitution in Ba2YCu3O7
Theo Siegrist,Lynn Schneemeyer,Joseph V. Waszczak,N. P. Singh,Robert L. Opila,Bertram Batlogg,L. W. Rupp,Donald W. Murphy +7 more
TL;DR: In this article, the effect of aluminum incorporation on the structure and superconducting transition temperature of single crystals of high cuprate perovskite superconductors was investigated and the importance of the Cu-O chains and oxygen stoichiometry to superconductivity was discussed.
Journal ArticleDOI
Temperature dependence of the magnetic penetration depth in the high-Tc superconductor Ba2YCu3O9- delta : Evidence for conventional s-wave pairing.
D. R. Harshman,G. Aeppli,Eduardo J. Ansaldo,Bertram Batlogg,J. H. Brewer,J. F. Carolan,Robert J. Cava,M. Celio,A.C.D. Chaklader,Walter Hardy,S. R. Kreitzman,Graeme Luke,D. R. Noakes,Masayoshi Senba +13 more
TL;DR: Transverse-field muon-spin-relaxation measurements have been performed on a superconductor and indicate a magnetic penetration depth of $\ensuremath{\lambda}\ensure Math{\approx}1400$ \AA{} which, in the limit of extreme anisotropy, reduces to $s$-wave with nodes in the gap function.
Journal ArticleDOI
Disappearance of superconductivity in overdoped La2-xSrxCuO4 at a structural phase boundary.
Hidenori Takagi,Robert J. Cava,M. Marezio,Bertram Batlogg,J. J. Krajewski,W. F. Peck,Pierre Bordet,D. E. Cox +7 more
TL;DR: In this paper, the electronic and structural phase diagram of heavily doped La and Sr was re-examined and the disappearance of superconductivity was shown to be associated with an orthorhombic to tetragonal structural phase transition near x = 0.2.
