The paper is concerned with the study of magnetic and magnetoresistive properties of ferromagnetic-metal monolayer films as well as the ascertainment of structure—phase effects within them. As shown, the total magnetization of Co, Fe, and Ni films increases with increasing their thickness. After the heat treatment, the total value of magnetization increases for Co and Ni films, while decreases for Fe films. After the heat treatment, the coercivity increases for all metal films, while pronounced size dependence for Co and Fe films in the unannealed state is not observed. For Co, Fe, and Ni films before and after the heat treatment, an anisotropic magnetoresistance dependence on the applied external magnetic field takes place.

Key words: thin films, ferromagnetic metals, magnetic properties, magnetoresistance, coercive force, total magnetization.
