| Abstract(in English) | Microwave surface resistance(R_s) of three types of YBCO films with different Cu composition was measured using 5-μm-wide and 18-cm-long coplanar transmission lines. The R_s of these films depends clearly on Cu composition : the films with Cu-rich composition have relatively low R_s of 110 μΩ at 10 K and 10 GHz and the decrease of Cu composition increases the R_s. The films with Cu-poor composition shows gradual decrease in R_s with decreasing temperature below T_c, which is quite different from the temperature dependence of two-fluid model. These Cu composition dependence correlate with the structure of the YBCO superconducting phase and the Cu deficiency in the YBCO phase caused the large R_s and the unique temperature dependence of R_s in the films with Cu-poor composition. |
