We studied magnetized topological insulator/superconductor junctions with the
expectation of unconventional superconductive states holding Majorana fermions induced by
superconductive proximity effects on the surface states of magnetized topological insulators (TIs),
attached by conventional superconductors. We introduced Fe-doped BiSbTe2Se as an ideal magnetic
TI and used the developed junction fabrication process to access the proximity-induced surface
superconducting states. The bulk single crystals of the Fe-doped TI showed excellent bulk-insulating
properties and ferromagnetism simultaneously at a low temperature. Meanwhile, the fabricated
junctions also showed an insulating behavior above 100 K, as well as metallic conduction at a low
temperature, which reflects bulk carrier freezing. In addition, we observed a proximity-induced gap
structure in the conductance spectra. These results indicate that the junctions using the established
materials and process are preferable to observe unconventional superconducting states which are
induced via the surface channels of the magnetized TI. We believe that the developed process can be
applied for the fabrication of complicated junctions and suites for braiding operations
