Abstract
Processing for the preparation of superconducting thin films by ion-beam sputtering is discussed. The main factors affecting the composition of the as-deposited films are analyzed, and the effects of various heat treatments on the properties of annealed films are studied. Superconducting BiSrCaCuO films on SrTiO3 substrates with an onset temperature of 115 K and a zero-resistance temperature of 78 K were successfully prepared. The films had apparent c-axis texture. By adopting a Pb layer diffusion method, Bi(Pb)SrCaCuO films with a high-T c phase were obtained
