Abstract: A method of modifying a domain structure of a magnetic ribbon is provided. The method includes a combination of stress and magnetic field annealing the magnetic ribbon in order to generate a desired permeability along one or more axes of the magnetic ribbon.

Abstract: A transformer includes a core formed of at least one MANC alloy. The MANC alloy has a predefined permeability.

Abstract: Various examples are provided related to mixed material magnetic cores, which can be utilized for shielding of eddy current induced excess losses. In one example, a magnetic core includes a ribbon core and leakage prevention or redirection shielding surrounding at least a portion of the ribbon core. The leakage prevention or redirection shielding can be positioned adjacent to the ribbon core and between the ribbon core and a magnetomotive force (MMF) source such as, e.g., a coil. The leakage prevention or redirection shielding extend beyond the ends of the MMF source and, in some implementations, can extend over the ends of the MMF source. In another example, a magnetic device can include a ribbon core, a MMF and leakage prevention or redirection shielding positioned between the MMF source and the ribbon core.

Abstract: A near-field probe (and associated method) compatible with near-infrared electromagnetic radiation and high temperature applications above 300° C. (or 500° C. in some applications) includes an optical waveguide and a photonic thermal emitting structure comprising a near-field thermally emissive material coupled to or part of the optical waveguide. The photonic thermal emitting structure is structured and configured to emit near-field energy responsive to at least one environmental parameter of interest, and the near-field probe is structured and configured to enable extraction of the near-field energy to a far-field by coupling the near-field energy into one or more guided modes of the optical waveguide.
