摘要:

Metal‐doped superconductor thick films Bi1.6Pb0.4M0.1Ca2‐Sr2Cu3Ox(M = V, Nb, Mo, In, Sn, Sb, and W) were prepared using a melt–solidification procedure. The optimum heat‐treatment temperatureToptwas observed in all the films with different dopants;Toptwas 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 lowerToptfor the formation of the 11
