摘要：

We study the renormalization of quasiparticle properties in weak ferromagnetic metals due to spin fluctuations, away from the quantum critical point for small magnetic moment. We explain the origin of the s-wave superconducting instability in the ferromagnetic phase and find that the vertex corrections are small and that Migdal's theorem is satisfied away from the quantum critical point.
