Surface Resistance of YBa(2)Cu(3)O(7) Films Deposited on LaGaO(3) Substrates

Abstract

Surface resistance (Rs) measurements on high-temperature superconductors are necessary to determine their suitability for practical applications. Several measurements of Rs for films of YBa2Cu3O7 (YBCO) on SrTiO3 have been made at various frequencies and temperatures. SrTiO3 is not the best substrate for high-frequency applications because of its high dielectric constant. A more suitable substrate is LaGaO3. Thin films of YBCO were deposited onto single-crystal (001) LaGaO3 substrates by either e-beam or magnetron sputtering techniques X-ray diffraction data showed that the films were highly c-axis and a-axis oriented with only trace amounts of impurities. Pole-figure analyses of selected films showed that all films were well aligned with the single-crystal substrate. (js)
