中文摘要 | Superconducting Pr1-xCaxBa2Cu3O7-delta (PCBCO) thin films with high Ca concentration (0.4 <= x <= 0.6) have been prepared. As characterized by x-ray diffraction, good quality c-axis and a-axis oriented epitaxial thin films are grown on SrTiO3 substrates by changing the substrate temperature. However, for each Ca concentration, higher zero resistance temperature (T-C0) is generally observed in samples with mixed orientations grown at moderate temperatures. The best T-C0 are 26.5 K, 34.1 K and 16.8 K for x = 0.4, 0.5 and 0.6 samples, respectively. Hall measurements reveal that the hole mobility decreases as x increases, while the Hall number n(H) reaches a maximum as x approaches 0.5, then reduces dramatically. It appears that the T-2 dependence of cot theta(H) is still feasible in this system, and the effect of Ca substitution on transport properties in PCBCO is a result of the competition between carrier introduction and carrier localization. |
