| Abstract: | We have measured the Hall resistivity, 
xy
, and the longitudinal resistivity,
xx
, in superconducting MgB2 thin films in a mixed-state while changing the magnetic field and the current density. A Hall scaling behavior without the anomalous Hall effect was observed with a exponent  of 2.0±0.1 in
xy
=A
xx
. This exponent is observed to be constant, i.e., independent of magnetic field, temperature, and current density. |
