Abstract
Superconducting Pb‐doped HgBa2CaCu2Oy films have been successfully synthesized on the (100) SrTiO3 substrate by laser ablation using a Pb‐doped Hg‐1212 target and post‐annealing. The as‐deposited film was post‐annealed with a pellet of the same powders as those of the target at 760 °C for 20 min in an evacuated quartz tube. The obtained film exhibited the (00n) oriented x‐ray diffraction pattern of the Hg‐1212. The superconducting transition temperature, Tczero, was 117 K. Anisotropy of magnetization, M(T) and M‐H curves in the directions of two different fields was confirmed.Keywords
