| 中文摘要 | The microwave surface resistance R-s of YBa2Cu3O thin film on LaAlO2 has been measured as a function of temperature and magnetic field through a resonant cavity technique. At zero field, the temperature dependence of R-s shows a BCS-like variation at higher temperatures and then tends to level off at lower temperatures. A general linear and square-root field dependence of R-s at low and high fields, respectively, has been obtained for both flux flow and pinning dominant regions based on the flux motion theory. The cross-over field H* from linear to square-root R-s(H) dependence was found to be very different for these two regions, In the flux flow region, H* linearly depends on the microwave frequency, white it is independent of the frequency in the flux pinning region. The experimental results for R-s(H) at about 10 GHz show a linear relationship at high temperatures and a transition from linearity to nonlinearity al low temperatures. The temperature dependence of the slope of the linear R-s(H) has been derived and can be well accounted for in terms of the flux flow model. The anisotropy of R-s(H) was measured in different magnetic and electrical field orientations. The results can be qualitatively expressed in terms of the flux motion theory. |
