Abstract

A bulk superconducting ceramic synthesized using solar technology exhibits a sharp increase in resistance from zero to approximately 160Ω at 250 K. Four thermal cycling tests in the range of 79-360 K revealed a tendency for the temperature transition interval to narrow and a comparatively sharp jump at 290 K, suggesting a superconducting transition. The effect of stress concentration at grain boundaries during four cycles leads to an increase in the superconducting transition temperature due to the cumulative rise in stress and pinning force. The assumption that these effects are caused by superconducting homologous phases is based on the manifestation of the Meissner effect in the studied sample.
