Abstract
Highly c-axes oriented 2212-phase films have been synthesized from the BiO1.5-CuO-(SrO,CaO) multilayers and uniform magnetron sputtered amor phous Bi-Sr-Ca-Cu-O precursors using postannealing in air at (700 divi ded by 850)degrees C. In situ high temperature XRD studies have been c arried out to elucidate mechanisms and kinetics of the two-layer phase formation. High crystalline quality of the 2212-phase films formed fr om the multilayers we associate with accelarated two-layer phase growt h in presence of fugitive liquid and intermediate Bi and Sr oxyde base d solid solution [1].
