Inclusion of a spin polarized solution demands an extension of the existing approximate parquet scheme so that both singlet and triplet multiple scatterings are treated on the same footing. We derived a workable scheme leading to a set of coupled self-consistent equations for the singlet and triplet vertices. We used this approximation to calculate the behavior of the spectral function in the strong-coupling regime in an applied magnetic field.
