Abstract
In the following survey a rather promising, simple, non-vacuum method of preparation of high-Tc (HTc) superconducting films synthesized by means of chemical deposition from an aerosol is described. Thin HTc films of YBCO, BSCCO and TBCCO systems were prepared by this method. Some details of the deposition process as well as the deposition technique are given. Properties of prepared YBCO, BSCCO and TBCCO films are presented. The best films, suitable eventually for high-temperature, high-current and high-field applications, are so far polycrystalline films of the TBCCO 1223 system prepared on polycrystalline YSZ substrates having Tc=104-107 K, and Jc=110 000 A cm-2/77 K, B=0; Jc=104 A cm-2/60 K, B=2 T, or Jc=105 A cm-2/4.2 K, B=9 T. Possible mechanisms of this high-current ability are discussed.Keywords
