Abstract Pb-doped HgBa₂CaCu₂O_y films were prepared on the (100) SrTiO₃ substrate by using laser ablation followed by post-Hg-vapor annealing. These films are dominated by c-axis-oriented Hg-1212 phase as indicated by x-ray diffraction and electromagnetic measurements. The transition temperature T_c0 is 110 K. The critical current density J_c achieved 10⁶ A/cm² at 77K and zero applied field.
