Latest Patents

One of Ru Ying Tong's latest patents focuses on Co/Ni multilayers with improved out-of-plane anisotropy for magnetic device applications. This invention describes a magnetic tunnel junction (MTJ) for a spintronic device that includes a thin seed layer designed to enhance perpendicular magnetic anisotropy (PMA) in an overlying laminated layer with a (Co/Ni) composition, where n ranges from 2 to 30. The seed layer is preferably made of materials such as NiCr, NiFeCr, Hf, or a composite thereof, with a thickness ranging from 10 to 100 Angstroms. Additionally, a magnetic layer like CoFeB may be formed between the laminated layer and a tunnel barrier layer to serve as a transitional layer between a (111) laminate and a (100) MgO tunnel barrier. The invention also suggests the inclusion of a Ta insertion layer between the CoFeB layer and the laminated layer to promote (100) crystallization in the CoFeB layer. This laminated layer can be utilized as a free layer in an MTJ, and annealing between 300°C and 400°C may be employed to further enhance PMA in the laminated layer.

Another patent by Ru Ying Tong also addresses Co/Ni multilayers with improved out-of-plane anisotropy for a domain wall motion device. Similar to the previous invention, it includes a thin seed layer that enhances PMA in an overlying laminated layer with a (Co/Ni) composition. The same materials and configurations are suggested, emphasizing the versatility and applicability of his innovations in various magnetic device contexts.
