Description

Structural changes in ceramics YBa2Cu3O7-x after Ar+7 irradiation with the energy 46.3 MeV have been studied by X-ray diffraction. It is shown that the main part of ceramics is transformed to amorphous phase during ion irradiation up to 3x1014cm-2 without any new crystal phases formation. A superconducting phase, which is remained after irradiation, exists in the form of recrystallized regions 400-500A in size. It is concluded that the degradation of critical parameters of yttrium high-temperature superconductors under heavy ion irradiation must be connected with ceramics amorphyzation but not with tetragonal transformation of the superconducting phase. 5 refs.; 4 figs
