Abstract

Fabrication of c-axis oriented $(Hg_{0.75}Rc_{0.25})Ba_2Ca_2Cu_3O_y$ thick fabricated has been attempted using Ni substrates with the buffer layer of Cr or NiO. Coexistence of $(Hg_{0.75}Rc_{0.25})Ba_2Ca_3Cu_4O_y$ pellets wad found to stabilize $(Hg_{0.75}Rc_{0.25})Ba_2Ca_2Cu_3O_y$ phase of the tape. The c-axis oriented tapes were reproducibly obtained on the NiO/Ni substerate and they recorded high $B_{irr}$ at 77K.$(Hg_{0.75}Rc_{0.25})Ba_2Ca_2Cu_3O_y$ 1223.
