In this work an intrinsic defects (atomic vacancies) in palladium and extrinsic defects (impurity phase) in copper were investigated. An intrinsic defects which are interpreted as atomic vacancies and divacancies distributed in a grains were found in submicrocrystalline (SMC) Pd. Intrinsic defects in SMC-Pd lead to the essential excess (8 %) of the magnetic susceptibility over that of the initial polycrystalline palladium. It is shown that the effect of microstructure on the susceptibility of plastically deformed palladium may be a consequence of the change in the density of states on the Fermi level. An extrinsic defects which are interpreted as superparamagnetic iron nanoparticles with a size of a few nanometers were found in SMC-Cu. Nanoparticles of Fe in diamagnetic matrix lead to increase of magnetic susceptibility of SMC-Cu. This increase is shown to be due to the Fe nanoparticles increasing in size from 2.8 to 3.3 nm. The vanishing of the ferromagnetic contribution by Fe nanoparticles is observed after annealing at 850 K, well below the Curie temperature of Fe, is due to the dissolution of nanoparticles in annealed Cu.
