摘要：
Co/Cu multilayers made by rf sputtering were studied with a vibrating sample magnetometer (VSM), ferromagnetic resonance (FMR) and magneto-optical (MO) spectra. The magnetization increases with decreasing thickness of Cu, which was attributed to the joint effect of interlayer coupling and 2D magnetism. Spin polarization of Cu related to interlayer coupling was indicated from the data of VSM and FMR measurements. The different feature of the experimental and calculated MO spectra further suggested that the Cu is spin polarized and gives an additional MO activity.
