Defect formation in the intermediate layers of YBa₂Cu₃O₇₋δ superconductors depending on oxygen сontents

Defect formation in the intermediate layers of YBa₂Cu₃O₇₋δ superconductors depending on oxygen сontents

In YBa₂Cu₃O₇₋δ superconductors with 0≤δ<0.6 the defect formation in the intermediate layers depending on oxygen content was revealed under γ-irradiation with doses 8-250 kGy. In YBa₂Cu₃O₇ the subthreshold creation of Ba, Cu1, O1 defects, which give rise to lowering of the annihilation rate of pos...
