Superconductivity at 93 K in a new mixed-phase Y-Ba-Cu-O compound system at ambient pressure
Maw-Kuen Wu,J. R. Ashburn,C. J. Torng,Pei-Herng Hor,R. L. Meng,Li Gao,Z. J. Huang,Yongmei Wang,Ching-Wu Chu +8 more
TL;DR: A stable and reproducible superconductivity transition between 80 and 93 K has been unambiguously observed both resistively and magnetically in a new Y-Ba-Cu-O compound system at ambient pressure.
Journal ArticleDOI
Evidence for superconductivity above 40 K in the La-Ba-Cu-O compound system.
TL;DR: An apparent superconducting transition with an onset temperature above 40 K has been detected under pressures in the La-Ba-Cu-O compound system synthesized directly from a solid-state reaction of La/sub 2/O/ sub 3/, CuO, and BaCO/sub 3/ followed by a decomposition of the mixture in a reduced atmosphere.
Journal ArticleDOI
Superconductivity above 90 K in the square-planar compound system ABa2Cu3O6+x with A=Y, La, Nd, Sm, Eu, Gd, Ho, Er and Lu.
Pei-Herng Hor,R. L. Meng,Yongmei Wang,Li Gao,Z. J. Huang,J. Bechtold,K. Forster,Ching-Wu Chu +7 more
TL;DR: The results suggest that the unique square planar Cu atoms, each surrounded by four or six oxygen atoms, are crucial to the superconductivity of oxides in general.
Journal ArticleDOI
High-pressure study of the new Yb-Ba-Cu-O superconducting compound system.
Pei-Herng Hor,Li Gao,R. L. Meng,Z. J. Huang,Yongmei Wang,K. Forster,J. Vassilious,Ching-Wu Chu,Maw-Kuen Wu,J. R. Ashburn,C. J. Torng +10 more
TL;DR: X-ray powder-diffraction studies show that the high-temperature superconductivity in Y-Ba-Cu-O can only be attributed to one or more phases with structures different from the cubic perovskite or tetragonal layered ones.
Journal ArticleDOI
Crystallographic description of phases in the Y-Ba-Cu-O superconductor
Robert M. Hazen,Larry W. Finger,Ross J. Angel,Charles T. Prewitt,Nancy L. Ross,Ho-kwang Mao,C. G. Hadidiacos,Pei-Herng Hor,R. L. Meng,Ching-Wu Chu +9 more
TL;DR: Single-crystal x-ray techniques were used to determine two structures that comprise the Y-Ba-Cu-O superconductor, related to a 1:1:3 AB perovskite: Ba and Y order in A sites and Cu is in B sites.
