  • STRAIN ENHANCEMENT OF FUNCTIONAL OXYGEN DEFECTS IN ELECTROCHEMICAL METAL OXIDES
    Publication number: 20170077522
    Abstract: Methods for tailoring an oxygen defect concentration, such as oxygen vacancies, in a transition metal oxide and the resulting materials are provided. An epitaxial strain, such as in the form of a biaxial tensile strain of up to 5%, is applied to the transition metal oxide to increase the oxygen defect concentration in the transition metal oxide to result in a product comprising the transition metal oxide having an increased oxygen defect concentration.

  • Nonvolatile corruption resistent magnetic memory and method thereof
    Patent number: 9047881
    Abstract: A method and system for storing information in a nonvolatile memory comprising: a substrate comprising magnetic material operatively associated therewith, the magnetic material having at least one first portion of low permeability and at least one second portion of high permeability; a reader comprising a sensor for reading information by measuring the magnetic permeability for the at least one first portion and the at least one second portion; whereby the at least one first and second portions are subjected to a magnetic probe field from one of an external source, the sensor, or a combination of an external source and the sensor.
    Type: Grant
