Laser deposition of quality high T/sub c/ superconductor films

The laser deposition technique has been developed into a versatile method for depositing films of YBa/sub 2/Cu/sub 3/O/sub x/ material. A brief description is given of the method and important materials characteristics, such as composition, surface smoothness, crystalline structure, and interactions with substrates. T/sub c/ over 93 K, J/sub c/ in the 10/sup 6/ A/cm/sup 2/ range at 77 K, tolerance to high magnetic fields, low temperature deposition (near 650 degrees C), as-deposited superconducting films, epitaxial growth, and very smooth surfaces have been demonstrated. Relevance to practical application is briefly discussed.<
