摘要：

Novel-textured Ag/(Bi,Pb) - Sr - Ca - Cu - O composite fibres have been grown by the laser floating zone method. Important parameters that have been studied include growing speed, silver content and post-annealing conditions. Polarized optical and scanning electron microscopy, a.c. and d.c. magnetic measurements and d.c. electric transport current have been used to characterize the final products. Silver addition has two main effects: it considerably improves the degree of texture within the fibre, and it lowers the melting point of the material. Moderate critical currents (J(c)(77 K) almost-equal-to 100 A cm-2) have been obtained with agreement between transport and inductive values.
