Pulsed-laser deposition was used to synthesize artificially layered high-temperature superconductors. Thin-film compounds were formed when the constraint of epitaxy was used to stabilize SrCuO[sub 2]-BaCuO[sub 2] superlattices in the infinite layer structure. Using this approach, two new structural families, Ba[sub 2]Sr[sub n-1]Cu[sub N+1]O[sub 2n+2+[delta]] and Ba[sub 4]Sr[sub n-1]Cu[sub n+3]O[sub 2n+6+[delta]], have been synthesized; these families superconduct at temperatures as high as 70 kelvin.
