Phys. Rev. Lett. 86, 1873–1876 (2001)Strong Vortex Liquid Correlation from Multiterminal Measurements on Untwinned YBa2Cu3O7-δ Single CrystalsReceived 18 September 2000; published in the issue dated 26 February 2001 Multiterminal transport measurements indicating a strongly correlated vortex liquid above the first order melting transition in untwinned YBa2Cu3O7-δ single crystals are presented. The correlation is found to be surprisingly stable for different weak variations of point disorder. We investigate the differences between intervortex and intravortex correlations in different contact geometries. The results are in agreement with the local conductivity model, with zero resistivity along straight vortex line segments. © 2001 The American Physical Society URL:
