Crystal growth of Bi2(SrxCa3−x)Cu2Oy with traveling solvent floating zone method

“…Ca 2+ , is simplified only from the influence of Sr/ Ca ratios. The dotted line in this graph represented the decreasing behavior of c-axis length facilitated by the decrease of Sr/Ca ratios within the sintered specimen [14]. Our data, listed in the last column in Table 2 in the range of Sr/Ca ratio from 1.32 to 2.05, the solid circles, correlate well with their results.…”

“…uller et al [14]. Hollow circles represent the compositions of single crystals obtained by Gu et al [19].…”

“…Fig. 2 indicates that the structural modification, induced by the cation substitutions of Bi 3+ , Sr 2+ , uller et al [14]. Various symbols represent the compositions of single crystals obtained by different groups [15][16][17][18][19].…”

“…And the nomenclature of the solvent rod was abbreviated as (Bi-%)(Cu-%)-(Sr/Ca ratio). [14] for Sr/Ca ratio of 1.9 and 1.6, respectively. According to the diagram, the lower left side of this triangle is Cudeficient.…”

“…uller et al [14] was considered herein for the starting composition of the feed rod. The single-phase region of Bi-2 2 1 2 was shaped like a triangular pyramid on their graph.…”
