Spin-active interfaces and unconventional pairing in half-metal/superconductor junctions
Spin-active interfaces and unconventional pairing in half-metal/superconductor junctions
We study the physical properties of a half-metallic $\text{ferromagnet}\ensuremath{\mid}\text{superconductor}$ $(\text{HM}\ensuremath{\mid}\text{S})$ bilayer, allowing for an arbitrary bulk pairing symmetry of the superconductor and spin-dependent processes at the interface. In particular, we study how the possibility of unconventional pairing such as $p$- and $d$-wave and a spin-active interface influence the (i) conductance …
