  • Patent number: 11054490
    Abstract: A magnetic field detection device includes a base, a first yoke, and a magneto-resistive effect element. The first yoke is provided on the base, and includes first and second principal surfaces each extending along a first plane, and a first end surface coupling the first and second principal surfaces. The magneto-resistive effect element is provided on the base, and includes a magnetization free layer disposed at a position overlapped with the first yoke in a first direction along the first plane. The first end surface includes an inverted tapered surface inclined relative to the first plane and extending closer to a center point of the magnetization free layer as being away from the base in a second direction orthogonal to the first plane. A distance from the center point to a first edge is shorter than a distance from the center point to a second edge.

  • Publication number: 20200348373
    Abstract: A magnetic sensor is provided with first and second magnetoresistive effect elements that can detect an external magnetic field. The first and second magnetoresistive effect elements are a plurality of layers of multilayer body including free layers where their magnetization directions vary due to the external magnetic field. Shapes of the first and second magnetoresistive effect elements viewed from the upper side in the lamination direction are different from each other. The first magnetoresistive effect element has a shape that can increase a slope of an output of the first magnetoresistive effect element relative to the change of the external magnetic field. The second magnetoresistive effect element has a shape that can decrease a slope of an output of the second magnetoresistive effect element relative to the change of the external magnetic field compared to the slope of the output of the first magnetoresistive effect element.
