| 中文摘要 | Resistive transitions and I-V isotherms of a Bi2Sr2.xLaxCuO6+sigma thin film have been measured in magnetic fields up to 5 T. A resistive transition showing a sharp jump to a very small value at a well defined temperature, T-c0(H), is observed. Using a Coulomb-gas (CG) model, we find that T-c0(H) can be considered as characterising a Kosterlitz-Thouless transition temperature, allowing all the resistive tails in different magnetic fields to fall onto a universal transition curve; besides, the scaling process also allows all the alpha (T, H) curves to fall onto a single alpha (T, H) scaling curve. These results suggest that T-c0(H) is related to the CG transition temperature above which the CG particles begin to be produced by the thermal unbinding of the vortex couplings. |
