The main issue addressed in present study is exchange coupling modification between ferromagnetic layers through non-magnetic spacer layers using extra ultra-thin ferromagnetic layers (Co). In order to achieve this goal, we prepared Cr(50Å) / Py(20Å) / Co(5Å) / Cr(7,10,13Å) / Co(5Å) / Py (30Å) / Cr(50Å) / Si using magnetron sputtering at UHV conditions and characterized by Ferromagnetic Resonance (FMR) technique. As the present study results were compared to our previous study on (Py/Cr), the exchange coupling energy was increased ten times with the cobalt thin layer
