抄録

Thallium based cupurate superconductors, TlSr₂Ca₂Cu₃O_y and TlSr₂Ca₃Cu₄O_y, were synthesized using a high-pressure technique. Synthesis condition was 2. 5 GPa, 1000°C for 4 hours for TlSr₂Ca₂Cu₃O_y, and 1. 5 GPa, 950°C for 4 hours for TlSr₂Ca₃Cu₄O_y. Lattice parameters were α=3. 823 Å and c=15. 33 Å for TlSr₂Ca₂Cu₃O_y, and α=3. 830 Å and c=18. 49 Å for TlSr₂Ca₃Cu₄O_y. The synthesis pressure and heating time were fairly critical to obtain single phases. T_c was 97 K and 90 K for TISr₂Ca₂Cu₃O_y, and TlSr₂Ca₃Cu₄O_y, respectively.
