@article{Sheng1988BulkSA, title={Bulk superconductivity at 120 K in the TlCa/BaCuO system}, author={Zhengzhi Sheng and Allen M. Hermann}, journal={Nature}, year={1988}, volume={332}, pages={138-139} }
The discovery of 30-K superconductivity in the LaBaCuO system1 and 90-K superconductivity in the YBaCuO system2 stimulated a worldwide search for even higher-temperature superconductors. Unfortunately, most of the higher-temperature transitions reported in the past year have proved to be unstable, irreproducible, or not due to bulk superconductivity37. Recently, we and co-workers8,9 reported superconductivity above 90 K in a new TlBaCuO system, and pointed out that elemental…
