Instantaneous preparation of superconducting thick films through melts in the Bi-Ca-Sr-Cu-O system

Thick films of Bi-Ca-Sr-Cu-O superconductors were instantaneously prepared by crystallization through melts on a MgO single-crystal substrate. It took only half an hour in annealing to obtain superconducting thick films with T c (zero) of 93 K and T c (onset) of 98 K. From the X-ray diffraction patt...

Description
Summary:Thick films of Bi-Ca-Sr-Cu-O superconductors were instantaneously prepared by crystallization through melts on a MgO single-crystal substrate. It took only half an hour in annealing to obtain superconducting thick films with T c (zero) of 93 K and T c (onset) of 98 K. From the X-ray diffraction patterns of these films, it was found that the superconducting phase was strongly oriented along the c -axis perpendicular to the substrate.
