Abstract
Hg-1212 films were prepared on the (100) SrTiO3 substrate by laser ablation and subsequent annealing. The as-grown film was annealed with a Hg-1212 bulk pellet in a quartz tube. The superconducting transition temperature T c(onset) was 123 K and T c(ρ=0) was 97 K. This film was shown to have a preferential orientation of the c-axis perpendicular to the (100) SrTiO3 substrate, and was composed of Hg-1212 platelike grains and Ba–Cu–O compounds.Keywords
