    摘要: Spin-transfer torque memory having a compensation element is disclosed. A spin-transfer torque memory unit includes a free magnetic layer having a magnetic easy axis and a magnetization orientation that can change direction due to spin-torque transfer when a write current passes through the spin-transfer torque memory unit; a reference magnetic element having a magnetization orientation that is pinned in a reference direction; an electrically insulating and non-magnetic tunneling barrier layer separating the free magnetic layer from the magnetic reference element; and a compensation element adjacent to the free magnetic layer. The compensation element applies a bias field on the magnetization orientation of the free magnetic layer. The bias field is formed of a first vector component parallel to the easy axis of the free magnetic layer and a second vector component orthogonal to the easy axis of the free magnetic layer. The bias field reduces a write current magnitude required to switch the direction of the magnetization orientation of the free magnetic layer.

    摘要: Aspects include methods to produce pattern media templates and the templates. A pattern of resist structures is formed on a first material layer. A conformal layer of a second material is deposited on the resist pattern, covering tops and side walls of the resist structures. The first material is more resistant to ion milling than the second material, and less resistant to plasma etching than the second material. The first material can be amorphous carbon and the second material can be aluminum oxide. The second material is removed on the tops, and preserved on the side walls. The resist structures and portions of the first layer not supporting second layer material are removed by plasma. The remaining structure is 2× denser than the resist pattern. Conformal deposition of second material and ion milling can be repeated. CMP removes the second material down to a portion of remaining first material, and remaining first material is removed by plasma, leaving a 4× denser pitch pattern structure formed from the second material.

    摘要: Embodiments of the invention provide a multi-terminal resistance device with first and second electrodes, a shared third electrode, and a resistance layer providing first and second current paths between the shared third electrode and the first and second electrodes, respectively. A current state of the device may be programmed by applying one or more electrical signals along the first and/or second current paths to change a resistance of the device. In some embodiments, applying an electrical signal may switch a junction resistance of the first and/or second electrodes and the resistance layer between two or more resistance values. The device may include a shared fourth electrode to provide extra programming capability. In some embodiments, the device may be used to store a data state, to determine a count of multiple electrical signals, or to perform a logic operation between two electrical signals.

    摘要: A bit patterned media (BPM) includes many magnetic dots arranged in tracks on a substrate. The magnetic dots each have a hard magnetic core, a soft magnetic cladding surrounding the core and a thin non-magnetic layer that separates the hard magnetic core from the soft magnetic ring. The soft magnetic cladding stabilizes the magnetization at the edges of the hard magnetic core to improve the signal to noise ratio of the magnetic dots. The soft magnetic rings also narrow the magnetic field of the dots which reduces the space requirements and allows more dots to be placed on the substrate.
