Stresses in superconductor during oxygenation

  • Ladislav CenigaEmail author


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.
