HgBa2Ca2Cu3O8+delta (Hg-1223) superconducting thin films of about 0.3 mu m in thickness have been successfully synthesized. The process involves depositing films(similar to 1 mu m thickness) of Ba2Ca2Cu3Ox on a SrTiO3 substrate by pulse laser ablation technique and implanting mercury ions into this deposited film, followed by annealing at oxygen atmosphere. The films so obtained show a relatively wide superconducting transition temperature up to 118 K, as determined magnetically, which is similar to that of underdoping bulk Hg-1223.
