The laser deposition technique has developed into a versatile method for depositing films of the YBaâCuâO/sub x/ material. A brief description of the method and important materials characteristics, such as composition, surface smoothness, crystalline structure, and interactions with substrates, are described. Tc over 93K, Jc in the 10ⶠA/cm² range at 77K, tolerance to high magnetic fields, low temperature deposition (near 650°C) as-deposited superconducting films, epitaxial growth, and very smooth surfaces have been demonstrated. Relevance to practical application is briefly discussed.
