We report about the preparation of lead-free Bi-Sr-Ca-Cu-O thin films of the 2212 phase by laser ablation. We have found an optimal regime for preparation, which makes it possible to produce films with T~0> 80 K andjc (60 K) > 106 A/cm 2 on SrTiO3 substrates. The films are characterized by current t
We have performed cross-sectional TEM/SAED and SNMS studies of film/substrate interactions in Bi2Sr2CaCu20 v ("2212") films on Si(lO0) substrates using Au, SiO 2, and Si3N 4 buffer layers. The 2212 "films were prepared by electron beam evaporation of stoichiometric targets in O 2 of 2x10 -4 mbar and
