Analytical model of oxygenation-induced stresses in YBCO superconductor

The paper deals with an analytical model of stresses in the YBCO superconductor during an oxygenation process to transform the tetragonal lattice of the non-superconductive phase YBa2Cu3O7−x0 (x0 = 0.9) to the orthorhombic one of the superconductive phase YBa2Cu3O7, the latter being required due to its zero electric resistance, and accordingly the oxygenation-induced stresses originate as a consequence of dimension changes of the crystalline lattices. Additionally, critical temperature of the oxygenation process with regard to crack formation in the YBCO superconductor is derived.
