Stresses in superconductor during oxygenation

Abstract

The paper deals with an analytical model of stresses acting in the superconductor YBCO during an oxygenation process to transform the tetragonal lattice of the non-superconductive phase \({\hbox{YBa}_2\hbox{Cu}_3\hbox{O}_{7-{x_0}} (x_{0}=0.9)}\) to the orthorhombic lattice of the superconductive phase \({\hbox{YBa}_2\hbox{Cu}_3\hbox{O}_7}.\) Accordingly, the oxygenation-induced stresses originate as a consequence of the difference in dimensions of the crystalline lattices. Additionally, critical temperature of the oxygenation process with regard to a crack formation in the superconductor YBCO is derived.
