Description
The effect of oxygen content on the defectivity and structure of the high temperature superconductor YBa2Cu3Oy (6.0 < y < 7.0) has been investigated using positron annihilation lifetime spectroscopy (LS) and thermally stimulated luminescence (TSL). Data analysis and comparison enabled a conclusion on positron trapping by metal (Ba,Cu) but not by oxygen vacancies (contrary to electrons). The trapping rate was sufficiently dependent on oxygen content in the sample. The transition range y between orthorombic (superconducting) and tetragonal (nonsuperconducting) phases was characterized by the increased content of not only oxygen but also metal (Ba,Cu) vacancies
