SYNTHESIS AND TRANSPORT PROPERTIES OF POROUS SUPERCONDUCTING CERAMICS OF YBa2Cu3O7-σ

Paweł Fiertek, Bartłomiej Andrzejewski and Wojciech Sadowski

Abstract

This work presents the method of producing an open porous structure that is based on a ceramic high superconductor YBa2Cu3O7-σ "filled with a sugar supplement". The results of the electric resistance measurements at different external magnetic fields are also presented. The obtained results have revealed a significant influence of the pore presence in the superconducting samples on the electrical resistance values, especially below the Tc temperature.
