Abstract

An amorphous NiP layer sputtered on glass substrate has an unique grain-like structure. The thin film media sputtered onto the NiP layer was found to have better grain isolation that leads to the reduction of the inter-grain interactions. The “grain size” of the NiP sub-seedlayer, which depends on the sputtering process and thickness, could affect the magnetic switching volume. Thus, by controlling the NiP “grain size” through optimizing the sputtering process and thickness, it is possible to obtain small and isolated magnetic grains fur thin film media on glass substrates
