Atomic structure and superconductivity in YBa2Cu3O(7-x)
Abstract
X-ray structural analysis of YBa2Cu3O(7-x) single crystals was performed before and after annealing in oxygen. An atomic mechanism for the transition from the tetragonal to the rhombic phase is established on the basis of the analysis, and atomic-structure elements connected with superconductivity are indicated.
