  • Method of making thin films
    Patent number: 11885009
    Abstract: A method of making a thin film can include bombarding a substrate with first ions supplied from a first ion beam; and sputtering from a metal sputtering target substantially simultaneously with the bombardment to deposit a metal-ion film onto the substrate, wherein the method is performed without applied heat, and the metal sputtering target comprises one or more of a metal, a transition metal, a semi-metal, alloys thereof and combinations thereof.
    Type: Grant
    Filed: February 12, 2019
    Date of Patent: January 30, 2024
    Assignee: UCHICAGO ARGONNE, LLC
    Inventors: Tomas Polakovic, Valentine Novosad
  • Ferromagnetic particles as ultra-sensitive non-linear response labels for magnetic particles imaging (MPI) and sensing applications
    Patent number: 11754648
    Abstract: A significant enhancement of detection capabilities of the room temperature MPQ is seen using optical lithography-defined, ferromagnetic iron-nickel alloy microdisks. Irreversible transitions between strongly non-collinear (vortex) and a collinear single domain states, driven by an ac magnetic field, translate into a nonlinear magnetic response that enables ultrasensitive detection of material at relatively small magnetic fields.
