Description
This paper reports on thin films in the Bi-Sr-Ca-Cu-O system which have been synthesized from liquid ethyl hexanoate precursors by spin pyrolysis. The extension of the ternary one-layer phase field into the quaternary system has been determined through the replacement of Sr by Ca in single-phase, c-axis oriented thin films. A significant Ca solubility in the one-layer phase was found, the maximum being around 0.4 per 1 Cu. All one-layer compositions were excess in Bi and deficient in (Sr + Ca) relative to the ideal composition and showed overall cation deficiency. The c lattice parameter and solids temperature were found to vary systematically with composition. The interpretation of the Ca solubility results in terms of Ca doping of the cation-deficient Sr sites and implications regarding the high-Tc Cu-layer phases in the system are discussed
