Description
It is found that there are ferromagnetic and paramagnetic contributions in the temperature dependencies of magnetization of Co/Cu (111) superlattices. The type of the samples [Co(8 A)/Cu(dCu)]20 (dCu = 9-21 A) were grown on a mica by using the magnetron sputtering method. They have a polycrystalline structure with a grain size of about 80-100 A. The numerical calculations have shown that the paramagnetic contribution in magnetization is formed by 48% of Co atoms contained in the sample. We have assumed that the most probable mechanism of the paramagnetic phase formation is connected with the diffusion processes at grain boundaries.
