    Research output: Contribution to journalArticlepeer-review


    A new mechanism for inelastic Andreev reflection at a ferromagnetic metal-superconductor interface is proposed, which consists of the simultaneous injection of a Cooper pair from the superconductor and the emission of a magnon inside the ferromagnet. We find that this process generates an additional contribution to the subgap non-linear I(V) characteristics, which is asymmetric with respect to the sign of the bias voltage and is related to the density of states of magnons in the ferromagnet.
