Study on the Preparation and the Physical Properties of a 110 K (Bi, Pb)2Sr2Ca2Cu3Oy Superconductor

Abstract
High-quality samples of 110 K superconductor (Bi, Pb)2Sr2Ca2Cu3O y were prepared in a single-phase polycrystalline form, which show resistivity at room temperature below 1 mΩ·cm and a zero-resistance temperature of 107 K. The Hall coefficient and the plasma frequency were measured in these crystals. The Hall coefficient and the plasma frequency obtained were 1×10-3 cm3/C and 8700 cm-1, respectively.
