尽管目前高温超导研究队伍状大,但还不能重复测量一年前YBa_2Cu_3O_(7-X)(YBCO)的记录93K以上转变温度的超导电性.这种情况现在已经发生变化.在本杂志55页Sheng和Hermann报道了Tl—Ba—Cu—O在85K以下具有超导性,随后的结果又表明钙部分取代钡使转变温度增加到大约115K。Maeda等人
Although the current HTS research team is large, the superconductivity of YBa_2Cu_3O_ (7-X) (YBCO) recorded over a year ago at 93K can not be repeated. This situation has now changed. Pages Sheng and Hermann reported that Tl-Ba-Cu-O has superconductivity below 85K, and the subsequent results again show that partial replacement of barium by calcium causes an increase in the transition temperature to about 115K.
