Abstract

The Hall conductivities of HgBa₂CaCu₂O_6+δ and HgBa₂Ca₂Cu₃O_8+δ thin films are investigated for a magnetic field parallel to the c-axis. The mixed-state Hall conductivity for these compounds is well described by σ_xy = C₁/H+C₂+C₃H. The prefactor C₁ shows a temperature dependence of the form C₁∝(1 - t)ⁿ near T_c, where t = T/T_c is the reduced temperature. Contrary to the previous results, C₂ also follows a temperature-scaling behavior similar to that of the coefficient C₁. The observed value of n, 1.8-2.3, is comparable to the previously observed values for YBa₂Cu₃O_7-δ and La_2-xSr_xCuO₄.
