Abstract
Hg-1212 films were prepared by means of annealing of mercury-free prec ursor films with bulk Hg-1212 pellets in an evacuated quartz tube. The mercury-free precursor films were deposited by laser ablation on (100 ) SrTiO3 substrates. The annealed films exhibited the (00n) oriented X -ray diffraction pattern of Hg-1212. The superconducting transition te mperature,T-c (rho = 0), was 121 K.
