Latest Patents

One of her latest patents is titled "Laminated magnetic thin films for magnetic recording with weak ferromagnetic coupling." This invention describes a laminated magnetic recording structure designed for both perpendicular and longitudinal recording. The innovation involves adding a small amount of ferromagnetic coupling between two magnetic layers that can switch independently. In this embodiment, the coupling is achieved by doping the spacer layer with a ferromagnetic material, such as Ruthenium (Ru), which is preferred for spacer layers alongside cobalt (Co). Additionally, the weak ferromagnetic coupling can be accomplished using platinum, palladium, and their alloys, with or without the addition of ferromagnetic elements. For perpendicular recording applications, the spacer layer may also include oxides of elements like Si, Ta, Ti, Nb, Cr, V, and B.

Another notable patent is "Perpendicular recording media having an exchange-spring structure." This recording medium enhances writeability in perpendicular recording applications. It features a magnetic recording layer with an axis of magnetic anisotropy that is substantially perpendicular to its surface. The exchange-spring layer is ferromagnetically exchange coupled to the magnetic recording layer and has a coercivity that is less than that of the magnetic recording layer. A coupling layer regulates the ferromagnetic exchange coupling between these two layers.
