  The spin-fluctuation based pairing mechanism has proven successful in
explaining the pairing symmetries due to Fermi surface nesting of both cuprates
and iron-based materials. In this work, we study signatures of a
spin-fluctuation mediated pairing at the local scale. Specifically, we focus on
magnetic impurities and calculate both the local antiferromagnetism and the
resulting modulated pairing interaction. The latter gives rise to distinct
local enhancements of the superconducting gap in the immediate vicinity of the
impurities. Our results show that Coulomb-driven pairing naturally leads to
unusual superconducting gap modulations near disorder potentials.
