Latest Patents

One of her latest patents is a tunnel junction device for the storage and switching of signals. This invention utilizes ferromagnetic-insulator-ferromagnetic trilayer junctions, which exhibit magnetoresistance (JMR) effects ranging from about 16% to several hundred percent at room temperature. The larger effects are observed when the tunneling resistance is comparable to the electrode film resistance over the junction area in cross-geometry junction measurements. The geometrically enhanced large JMR can be qualitatively explained by the nonuniform current flow over the function area when the tunneling resistance is comparable to the electrode film resistance. For a fixed junction area, the effective junction resistance can be varied from less than 1 ohm to several kilohms by controlling the thickness of the insulating layer or by appropriately selecting ferromagnetic films. The trilayer tunnel junctions of this invention are nonvolatile, stable, and reproducible.

Another notable patent is an electron tunneling device using ferromagnetic thin films. This device has shown over 10% change in the junction resistance with magnetic fields less than 100 Oe at room temperature, although the effect decreases at high DC bias across the junction. Utilizing such junctions as magnetic sensors or memory elements offers several advantages, including the ability to create submicron sizes with high junction resistance and low power dissipation. The magnitude of the effect aligns with the simple model of spin-polarized tunneling between ferromagnets.
