Abstract
The influence of the Zn impurity has been studied in the superconducting compound YBa2Cu3O7−δ by using two different methods of preparation: substitution of Cu by Zn or addition of Zn at the starting materials. In both cases scanning electron microscopy and electron probe microanalysis studies of the superconducting phase show a substitution of copper by zinc in a partial amount only. The effect of Zn on the superconducting properties of YBa2Cu3O7−δ is found to be quite different from the influence of magnetic impurities.
