摘要：

The effect of deposition temperature of Y1Ba2Cu3O7-x thin film on the microwave surface resistance R-s has been studied for films deposited in-situ by cathodic sputtering on MgO (100) single crystal substrate and compared to results obtained on LaAlO3 (100) single crystal substrates. The measurements of R-s were performed at 10 GHz and 77 K using the dielectric resonator method. It was found that YBa2Cu3O7-x films where R-s values are lower than 0.5 m Omega were obtained on MgO substrate within an extremely narrow temperature range (1-2 degrees C). The presence of the lowest R-s values were found to be correlated with the lowest RBS yield in channelling geometry (chi(min) and with the lowest quantity of misaligned c-asis grains.
