Attempts have been made to prepare various high-T c superconducting intercalation compounds, M+X+Bi 2 Sr 2 Ca nΨ1 Cu n O 2nΨ4Ψ (Mβ«Ψβ¬metal; X β«Ψβ¬ halogen; n β«Ψβ¬ 1, 2, and 3), with the synthetic strategy of hard+soft+acid+base interaction. The chimie douce route such as vapor transport and ionic di4us
A description of a novel current-lead design is given together with an assessment of the heat leakage into a liquid helium cryostat. Calculations indicate that the heat leak using these novel current-leads is of the order of ten times less than the leak that would be obtained using optimized convent
