摘要：

Thin films belonging to the family of Spin Ladders (Sr,Ca)(h-1)Cuh+1O2h are grown by MBE, The deposition is performed under atomic oxygen using real time control by the RHEED intensity. The structural parameters measured by four-circle X-ray diffraction agree with the values observed for cuprate Spin Ladders in bulk compounds from various laboratories. HRTEM images shows the double Cu rows within the CuO planes which are characteristic of ladder structures. The room temperature resistivity ranges from 1 m Omega.cm for Ca2Cu4O6 to 1 Omega.cm for Sr2Cu4O6. Doping with BiO planes was tested. A superconducting transition at 40K was observed in a BiSrCaCuO compound with a composition compatible with two-leg ladders.
