Abstract
The spill magnetic susceptibility of the p-d model is calculated by means o f a perturbation theory in the hybridization term V through a generalized c umulant expansion (GCE). The analysis is approached from the paramagnetic m etallic phase. The results qualitatively reproduce some unusual magnetic pr operties in the normal state of the hole-doped cuprates, supporting the sce nario of a Van Hove singularity near the Fermi level.
