Özet

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(50 angstrom) / Py(20 angstrom) / Co(5 angstrom) / Cr(7, 10, 13 angstrom) / Co(5 angstrom) / Py (30 angstrom) / Cr(50 angstrom) / Si using magnetron sputtering at UM' 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
