  • Patent number: 11449784
    Abstract: In many cases after degaussing the field distribution in a magnetic material there may be regions within the magnetic material that have ordered domains that contribute a remnant field. There is the need to reduce or eliminate non-uniform fields within a volume of interest left after degaussing a magnetic shield. Degaussing coils surrounding a metal shield can be used to favorably order magnetic domains within the material to counteract the remnant fields left behind following imperfect degaussing. The remnant field value can be measured and a small current may be applied through the degaussing coils. After removing the current, the field can be measured again and a higher current may be applied again through the coils. Repeated applications of currents and field measurement will progressively order domains in the direction of the applied field, resulting in a reduction of the net field and lower field gradient across the volume of interest.

  • Patent number: 11443879
    Abstract: An integrated magnetic device has a magnetic core which includes layers of the magnetic material located in a trench in a dielectric layer. The magnetic material layers are flat and parallel to a bottom of the trench, and do not extend upward along sides of the trench. The integrated magnetic device is formed by forming layers of the magnetic material over the dielectric layer and extending into the trench. A protective layer is formed over the magnetic material layers. The magnetic material layers are removed from over the dielectric layer, leaving the magnetic material layers and a portion of the protective layer in the trench. The magnetic material layers along sides of the trench are subsequently removed. The magnetic material layers along the bottom of the trench provide the magnetic core.
