  • Magnetic field detection sensor exhibiting a monotonous decrease in impedance from zero magnetic field
    Patent number: 10627457
    Abstract: A magnetic field detection sensor includes a magneto-impedance element and detects an external magnetic field from an output obtained by applying alternating current to the magneto-impedance element using a magneto-impedance effect. The magneto-impedance element includes a non-magnetic board and a magnetic film formed on a surface of the non-magnetic board, a longitudinal direction of the magnetic film is set as a detection direction of the external magnetic field, and magnetic anisotropy is provided such that a magnetization easy axis of the magnetic film is the same as the detection direction of the external magnetic field. The magnetic field detection sensor further includes a magnetic field generating portion which generates a magnetic field in a thickness direction of the magnetic film.
