abstract
Since the 1960s, Nb-Ti, exhibiting a superconducting transition temperature Tc of 9K, and Nb3Sn, with a Tc of 18K have been the materials of choice for superconducting applications. The prospects for the future changed dramatically with the discovery of ceramic high temperature superconductors exhibiting Tc values well above the boiling temperature Of liquid nitrogen (77K). These materials are now widely considered for large power applications, electronics and magnets including a.o. power transmission cables, motors, generators, fault current limiters, transformers, NMR and MRI. The fabrication of useful conductors out of these layered cuprates encountered some problems in areas such as chemical and structural purity, stability, oxygen stoichiometry and weak links. However, a first generation of silver sheathed composites based on Bi2xPbxSr2Ca2Cu3O10 has already been commercialised. It is now a widespread view that superconducting wires with high performance under strong magnetic fields and at elevated temperatures above liquid nitrogen, will need to be realised using the (RE)Ba2Cu3Oy materials. Because of the weak link nature of these materials, a second generation of biaxially aligned coated conductors was developed As a consequence, many deposition techniques have been studied to grow thin films of the superconducting (RE)Ba2Cu3Oy and adequate buffer layers on suitably prepared textured substrates. In this paper, the critical parameters in the deposition of thin films using vacuum and non-vacuum techniques will be reviewed. Finally, this review will address the measurement of the obtained properties of these coated conductors. The most important practical characteristic of a superconductor is its critical current density. Spectroscopic methods such as I.R. play an important role in the development of adequate precursors for chemical solution deposition of thin films. Finally, microstructural analysis using XRD, SEM and TEM is important to reveal the relation of these features on the transport properties of the films.
