S. Kishida et al., EFFECTS OF COOLING RATES AND TEMPERATURES ENDING THE GROWTH ON BI2SR2CACU2OY SINGLE-CRYSTAL GROWTH, Physica status solidi. a, Applied research, 151(1), 1995, pp. 17-22
Bi2Sr2CaCu2Oy single crystals are prepared by a self-flux method using
the crucible with a cap. From the results, it is found that the optim
um cooling rate and the optimum temperature ending the growth are 1 K/
h and 830 degrees C, respectively. A plate-like Bi2Sr2CaCu2Oy single c
rystal with the size of 6 x 2 mm(2) is obtained which is 80 K single-p
hase.
