Résumé : 

We consider a Dirac operator H with non-constant magnetic field of constant direction, perturbed by a sign-definite matrix-valued potential V decaying fast enough at infinity. Then we present asymptotics, as the energy goes to +m and -m, of the spectral shift function for the pair (H,H+V).
