The injection of pure spin current into superconductors by the dynamics of a ferromagnetic contact is studied theoretically. Taking into account the suppression of the order parameter at the interfaces (inverse proximity effect) and the energy-dependence of spin-flip scattering, we determine the temperature-dependent ferromagnetic resonance linewidth broadening. Our results compare well with recent experiments in Nb|permalloy bilayers (Bell C. et al., Phys. Rev. Lett., 100 (2008) 047002).
