41. As a matter of principle, such features are typical not only for junctions between ferromagnets and BCS superconductors, but also for HiTc materials, since subgap transport through any spin singlet superconductor would be affected by spin current mismatch at the F-S interface. For a matching pair of materials, with the Curie temperature of the ferromagnet similar to the transition temperature of the HiTc material, the Andreev reflection process could be used to probe a broader part of the magnon spectrum.
