摘要：

We measure the longitudinal (rho(xx)) and Hall (rho(xy)) resistivities as a function of magnetic field and temperature in the mixed state of epitaxial YBa2Cu3O7 films. We observe a striking power-law behavior rho(xy)(T) is-proportional-to [p(xx)(T)] at fixed field, with alpha = 1.7 +/- 0.2. Our results link the Hall behavior to collective behavior in the presence of pinning. In addition, this power-law dependence is consistent with new calculations for the vortex-glass transition, and therein may provide the first measurement of a new critical exponent.
