High‐T_c superconducting thin films

Abstract

Abstract This review describes recent advances in thin film studies of high‐T c superconducting cuprates. Emphasis is placed on epitaxial thin film growth technologies for LnBa 2 Cu 3 O x (Ln = Y, Eu) cuprates, and on microwave device applications. An exciting area of this research involves epitaxial multilayer structures, such as a superconductor/insulator/superconductor (SIS) combination, and so preliminary results on SIS fabrication are also described.
