Abstract

We have measured the longitudinal resistivity and the Hall resistivity in the ab plane of highly c-axis-oriented MgB₂ thin films. In the normal state, the Hall coefficient (R_H) behaves as R_H∼T with increasing temperature (T) up to 130 K and then deviates from that linear T dependence at higher temperatures. The T² dependence of the cotangent of the Hall angle is only observed above 130 K. The mixed-state Hall effect reveals no sign anomaly over a wide range of current densities from 10² to 10⁴ A/cm² and for magnetic fields up to 5 T.
