Within the scope of the adsorption approach to the description of epitaxial layer electronic structures, analytical expressions for magnetization of cumulene and polyyne formed on magnetic substrates have been obtained. To describe the densities of states of Fe, Co and Ni subbands, Friedels model were used. It has been shown that the spin moment of carbon adatom is proportional to the spin shift between σ-subbands. Keywords: cumulene, polyyne, occupation number, magnetic moment.
