- Title

- Abstract
We study pairing by the exchange of spin-wave excitations near the ferromagnetic or antiferromagnetic instability in terms of the effective two-particles T-matrix. We show that near the ferromagnetic instability the paring due to the exchange of the paramagnetic excitations can occur in the p-wave state (ℓ=1) and m=±1. We show that near the antiferromagnetic instability the pairing due to the exchange by the paramagnetic excitations occurs also in the p-wave state (ℓ=1) but with m=0 and that there is no pairing in d-wave state.
