OXIDE MATERIAL FOR SHOWING SUPERCONDUCTIVITY AND METHOD OF ITS PREPARATION |
| 摘要 |
The present invention comprises novel oxide materials exhibiting bulk superconductivity up to and exceeding 85K and processes for their synthesis. The oxides are within the formula RaBabCucOd wherein 1.9<a<2.1, 3.9<b<4.1, 6.8<c<7.2, 14.4<d<15.2 and wherein R is Y or any of the lanthanide rare earth elements. Certain substitutions such as Ca and La on the R and Ba sites are included. |
