Abstract :
The laser deposition technique has been developed into a versatile method for depositing films of YBa2Cu3Ox material. A brief description is given of the method and important materials characteristics, such as composition, surface smoothness, crystalline structure, and interactions with substrates. Tc over 93 K, Jc in the 106 A/cm2 range at 77 K, 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
