  • Publication number: 20130229862
    Abstract: Spin-transfer torque memory includes a composite free magnetic element, a reference magnetic element having a magnetization orientation that is pinned in a reference direction, and an electrically insulating and non-magnetic tunneling barrier layer separating the composite free magnetic element from the magnetic reference element. The free magnetic element includes a hard magnetic layer exchanged coupled to a soft magnetic layer. The composite free magnetic element has a magnetization orientation that can change direction due to spin-torque transfer when a write current passes through the spin-transfer torque memory unit.

  • Publication number: 20050175863
    Abstract: A novel method of manufacturing a novel recording media is disclosed. The manufacturing method includes obtaining a substrate having an inside diameter and an outside diameter and creating a radial profile of an intensive property, such as Hc, of a multilayer magnetic layer containing at least a first magnetic layer and a second magnetic layer deposited on the substrate, from the inside diameter to the outside diameter by forming a radial profile of an extensive property, such as MrT or T, of either the first magnetic layer or the second magnetic layer from the inside diameter to the outside diameter.
