摘要: We present experimental results on longitudinal magneto-optic Kerr effect in composite systems based thin Fe layers associated with amorphous alumina (Al 2 O 3 ). [Al /Fe] m -samples () have been prepared by rf magnetron sputtering onto Si(100) substrate. investigated the of Al and thicknesses rotation. The geometry multilayers is predicted theoretically using deduced magneto-optical constants. It will be shown how large rotation values can obtained adjusting sample parameters. For instance, a close to 7° has observed from an /Fe/Al /Fe/Si multilayer. reflectivity figure merit are discussed as function thickness.
