Abstract

Bi‐Pb‐Sr‐Ca‐Cu‐0 superconductors were prepared by the laser pedestal growth method. The high Tc phase was created only by post annealing. As the growing speed increased, the annealing time necessary to obtain a Tc above 100K decreased. When the low Tc phase was aligned with the growing direction, Tc was under 100K, but a Jc of 15B0A/cm2(77.3K, OT) was obtained. In this case, magnetic field dependence below 300 gauss was superior to that of Pb‐free materials.
