High Temperature Superconductivity at 90 K in Orthorhombic LaBa_2Cu_3O_y
スポンサーリンク
概要
- 論文の詳細を見る
A LaBa_2Cu_3O_y sample with an orthorhombic crystal structure was synthesized. It showed superconductivity with an onset temperature of 95 K and zero resistance at 80 K (midpoint 90 K). From the magnetic susceptibility measurement, about 30% of the whole volume of the sample was found to be the 90 K superconducting phase. The 90 K superconducting phase in LaBa_2Cu_3O_y is thus considered to have an oxygen defect perovskite structure which is most probably identical to that of the typical 90 K superconductor orthorhombic LaBa_2Cu_3O_y.
