Structural and superconducting properties of magnetically doped Bi-2212 textured rods grown by laser floating zone (LFZ) technique

In this work, we have applied the laser floating zone technique, a well-known method to produce highly aligned crystals and dense morphology, with improved transport properties, to obtain Bi2Sr2Ca1Cu2−x Ni x O (x=0, 0.01, 0.03, 0.05 and 0.1) fibers of about 1.8 mm diameter ×12 cm length. Microstruct...
