摘要：

The Hall resistivity rho(H) and the longitudinal resistivity rho of single crystalline Bi2Sr2CaCu2Ox are measured in the thermally activated flux flow regime. It is shown that rho(H) scales to a universal function of rho: rho(H)(T) = A[rho(T)]beta, where beta = 2 +/- 0.1 and A is a positive and magnetic field independent coefficient for magnetic fields from 1 to 5 T. A resistivity-squared dependence of rho(H) can be explained by the recent theory of Vinokur, Geshkenbein, Feigel'man, and Blatter in terms of weak pinning of a vortex liquid.
