Abstract

The temperature and the magnetic-field dependences of both the Hall resistivity ρ_xy and the longitudinal resistivity ρ_xx in the mixed state of c-axis-oriented Hg_0.9Tl_0.1Ba₂Ca₂Cu₃O _8+δ superconducting films with T_c > 124 K have been measured. It is found that the Hall resistivity ρ_xy shows a sign anomaly and scales with the longitudinal resistivity ρ_xx as ρ_xx(T) = Kρ^β_xx(T) with β ≈ 1.8 and a magnetic-field-independent coefficient K.
