Superconducting Properties of Bscco (2223) Ultrathin Films

Abstract

Ultrathin films of (Bi–Pb)–Sr–Ca–Cu–O (2223) were produced by ex situ RF magnetron sputtering on MgO (100) substrates. Films with different thermal treatments and thickness varying between 30 nm and 300 nm were obtained and studied systematically. A structural characterization of these samples was carried out and correlated with their electrical properties and thickness.

“…This method is known as an ex-situ preparation of the HTS materials. Ex situ techniques have been successfully applied in the preparation of BSCCO (2223) ultra thin films [4], YBCO (123) thin [5] and thick films [6].…”
