Abstract

In this paper, the optimization and amplification of magneto-optical response of Si/Cobalt nanowires in the presence of ZnS and SiO2 thin layers were investigated. The existence of ZnS layer with ideal thickness on the Si/Cobalt structure, leads to an appropriate optical cavity which amplifies the magneto-optical Kerr signal. In addition, the capping layer, SiO2, which is useful in manufacturing process, acts as a complementary layer for ZnS layer. The proposed structure Si/Co/ZnS/SiO2 with appropriate thicknesses enhances the Kerr signal of Si/Co-nanowire up to 20 times related to same structure without covering layers.
