摘要：
We have studied vortex correlations in single crystals of Ba1-xKxBiO3 by means of multiterminal transport measurements in magnetic fields up to 12 T. The pseudo flux-transformer geometry was used to probe the vortex correlations in the vortex liquid as a function of temperature and field. The vortex system is found to be correlated over the sample thickness just above the onset of resistivity for low to intermediate applied fields. The observed loss of vortex correlation at higher fields is attributed to pinning.
