  • Publication number: 20230358828
    Abstract: At a reference position within a first plane, a magnetic field to be detected has a first direction that changes within the first plane. A magnetic sensor includes an MR element. The MR element includes a magnetic layer having first magnetization that can change in direction within a second plane. The first plane and the second plane intersect at a dihedral angle ? other than 90°. The magnetic field to be detected can be divided into an in-plane component parallel to the second plane and a perpendicular component perpendicular to the second plane. The in-plane component has a second direction that changes with a change in the first direction. The direction of the first magnetization changes with a change in the second direction. A detection value depends on the direction of the first magnetization.
