Abstract :
The interlayer exchange coupling strength of 80Ni-Fe/Cu multilayer films prepared on a glass substrate by magnetron sputtering was studied by ferromagnetic resonance. The exchange coupling strength was evaluated by assuming a weak perpendicular magnetic anisotropy and fitting the data of the resonance fields and peak intensities. It exhibited a broad peak when the Cu thickness was 10.8Ã…, and increased linearly in proportion to the number of bilayers.
