Abstract:
Perpendicular magnetic media are described for use in magnetic recording and data storage. For example, a magnetic medium may include a substrate, a layer of titanium formed over the substrate, a layer of platinum formed over the layer of titanium, and a multi-layered magnetic stack formed over the layer of platinum. The layer of titanium provides a seed layer to improve the crystal texture of the layer of platinum. The layer of platinum, in turn, provides a seed layer to improve the crystal texture of the multi-layered magnetic stack. In this manner, high perpendicular magnetic anisotropy can be achieved and storage densities can be increased.
