  • Publication number: 20150331071
    Abstract: An omnidirectional magnetoresistive magnetic field sensor includes a plurality of magnetic material film layers each having an equal thickness of less than 0.5 nanometers (nm), and a plurality of non-magnetic spacer layers between each of the magnetic material film layers.
    Type: Application

  • Patent number: 8773821
    Abstract: A mixed anisotropy magnetic field sensor includes a first magnetic material film having in-plane anisotropy with a first magnetic easy axis that is in-plane, a second magnetic material film having out-of-plane anisotropy with a second magnetic easy axis that is perpendicular to the first magnetic easy axis of the first magnetic material film, and a non-magnetic spacer between the first magnetic material film and the second magnetic material film. The first magnetic material film has a magnetization oriented in a first magnetization orientation parallel to the first magnetic easy axis in the presence of no applied magnetic field, and the second magnetic material film has a magnetization oriented in a second magnetization orientation parallel to the second magnetic easy axis in the presence of no applied magnetic field.
