文摘
- •
Andreev reflection and resulting subgap conductance in a $MoS_2$-based ferromagnetic superconductor are investigated.
- •
The accurate form of electron-hole excitations and corresponding Dirac-like spinors are exactly obtained.
- •
we consider the difference of superconducting gap under electron-hole converting, taking place in the $d$-wave order.
- •
Strong spin-splitting occurs in valence band of nondegenerate $K$ and $K′$ valleys due to exchange field.
- •
Exchange energy causes a distinct behavior in Andreev process between spin-up and spin-down charge carriers.
