Spin Transport in High‐Field Superconductors

High-field superconductors are characterized by a spin splitting of the density
of states, giving rise to spin transport phenomena. This includes
spin-polarized tunneling, spin-dependent thermoelectric effects, long-range
quasiparticle spin transport, and spin-dependent coupling of supercurrents
and quasiparticles. This review gives a brief overview of the theory
background, recent experimental progress in the field, and an outlook on
open problems and possible applications.
