| Abstract: | Metal-doped superconductor thick films Bi1.6Pb0.4M0.1 Ca2-Sr2Cu3Ox (M = V, Nb, Mo, In, Sn, Sb, and W) were prepared using a melt–solidification procedure. The optimum heat-treatment temperature T opt was observed in all the films with different dopants; T opt was related to the temperature at which a partial melting of the films occurred as determined by differential thermal analysis. The dopants in the melt-solidified films lower the partial melting temperature and thus lower T opt for the formation of the 110 K phase. |
