The paper is devoted to general laws impact layer thickness based on Gd and thickness of the ferromagnet on the value of magnetoresistance and coercivity in layered films Fe / а-Gd / Fe and Co / а-Gd / Co at different measurement geometry and orientation angles of the samples in an external magnetic field. Found that the greatest value of magnetoresistance observed in perpendicular geometry measurement. It is shown that by changing the thickness of the а-Gd layer and the upper layers of ferromagnetic value of magnetoresistance and coercivity has oscillatory character.
