摘要: We describe the fabrication of PbSn‐coated, 2.5‐μm‐thick, Mylar ribbons that can be used as electrical leads in low‐temperature experiments. present measurements thermal conductivity and uncoated between 0.08 2.0 K. At 0.1 K, a conveniently sized coated lead has same conductance an ∼6‐μm‐diam manganin wire length.
