摘要：

Superconducting Bi-Sr-Ca-Cu-O films were prepared through a metal alkoxide route. The superconducting thin films composed of high Tcand low Tcphases with (00l) preferred orientation were successfully prepared at 850°C for 30 min on MgO(100) single-crystal substrates by a dip-coating method using partially hydrolyzed metal alkoxide solutions with 2-dimethylaminoethanol. The high TcBi2Sr2Ca2Cu3Oxphase was found to form from the Bi2Sr2CuOxphase through the low TcBi2Sr2CaCu2Oxphase in the Bi-Sr-Ca-Cu-O system. The preferentially orientated thin films prepared at 850°C exhibited the superconducting transition with an onset of 114 K and an offset of 65 K. © 1990 IOP Publishing Ltd.
