This work presents a study of Ga+ ion implantation of polycrystalline hcp cobalt thin films and nanostructures. It is shown that Ga+ ion implantation leads to a substantial modification of magnetic properties including large coercivity increase and s

Spin-valve structures might be exposed to higher temperatures in future disk drive applications and might thus degrade faster than it does today if proper materials and methods are not used. In order to determine whether this degradation is due to in

Signal degradation in spin-valve structures is today a concern for long-term stability of data storage devices. One of the possible degradation mechanisms of spin-valve structures in disk drive applications could be thermally activated diffusion betw

We have investigated Co/Pd multilayers deposited on either Ta or indium tin oxide (ITO) seed layers as a potential perpendicular recording media. We have examined the microstructural evolution of the films deposited on the two different types of seed

The effects of the RuxCr1−x/Ta underlayer on the microstructural and magnetic properties of CoCrPtB perpendicular films were investigated. The hcp RuxCr1−x (0002) texture was observed to grow perpendicular to the film plane with narrow rocking cu
