ABSTRACT:
A superconducting oxide ceramic pattern is described. The pattern is comprised of a high Tc superconducting region and a low Tc superconducting region which exhibits a resistivity at the liquid nitrogen temperature while the high Tc region is superconductive at that temperature. The low Tc region is doped with impurity such as Si and then subjected to thermal treatment to oxidizing the impurity.
