Twin formation and structural modulations in orthorhombic and tetragonal YBa2(Cu1−xCox)3O7−δ
Wolfgang W. Schmahl,Andrew Putnis,Ekhard K. H. Salje,P. Freeman,A. Graeme-Barber,R. Jones,K. K. Singh,J. Blunt,Peter P. Edwards,John Loram,K.A. Mirza +10 more
TL;DR: The microstructure of YBa2(Cu1−xCox)3O7−δ, prepared by the standard ceramic method, shows lamellar twin structures with decreasing spacings between twin walls with increasing Co content for x≲0·02, developing into {110}-type cross-hatched "tweed" modulation for x ≥ 0·02 as discussed by the authors.
Journal ArticleDOI
Ionic and metallic clusters of the alkali metals in zeolite Y
Martin R. Harrison,Peter P. Edwards,Jacek Klinowski,John Meurig Thomas,David W. Johnson,C. J. Page +5 more
TL;DR: In this article, electron spin resonance (ESR) spectroscopy was used to detect stable ionic cluster species Na3+4 and Rb 3+4 in dehydrated samples of zeolite Y containing alkali-metal cations.

Journal ArticleDOI
Composition-controlled metal-insulator transitions and minimum metallic conductivity in the oxide systems LaNi1−xMxO3 (M = Cr, Mn, Fe, or Co)
TL;DR: In this article, the authors investigated the metal-insulator transition in perovskite systems LaNi1-xMxO3 (M = Cr, Mn, Fe, and Co) by transport measurements over the temperature range 12-300 K.
Journal ArticleDOI
Superconductivity up to 90 K in a New Family of the (Pb,Hg)Sr2(Ca,Y)Cu2O7 System
TL;DR: In this article, a new family of superconductors were observed in the (Pb0.5Hg 0.5)Sr2(Ca1-xYx)Cu2O7-δ system, with a maximum Tc of 90 K (at x = 0.2, and c ranging from 11.5 to 12.2).
