摘要：

The mixed-state Hall resistivity rho(xy) and the longitudinal resistivity rho(xx) in superconducting MgB2 thin films have been investigated as a function of the magnetic field over a wide range of current densities from 10(2) to 10(4) A/cm(2). We observe a universal Hall scaling behavior with a constant exponent beta of 2.0+/-0.1 in rho(xy)=Arho(xx)(beta), which is independent of the magnetic field, the temperature, and the current density. This result can be interpreted well within the context of recent theories.
