文摘

Ferromagnetic and superconductivity coexistence in 3-dimensional topological insulator is considered. Superconducting electron-hole excitation is significantly affected by the magnetization of ferromagnetic order. Majorana mode along the interface sensitively depends on the magnitude of magnetization in FS region. Antiparallel configuration of magnetizations results in magnetoresistance in N/F/FS junction. Andreev reflection at the 3DTI F/FS interface is more or less suppressed.
