  • MAGNETIC BALANCE TYPE CURRENT SENSOR
    Publication number: 20120306491
    Abstract: A magnetic balance type current sensor of the present invention includes a magnetic field detection bridge circuit including four magnetoresistance effect elements whose resistance values change owing to application of an induction magnetic field from a current to be measured. Each of the four magnetoresistance effect elements includes a ferromagnetic fixed layer formed by causing a first ferromagnetic film and a second ferromagnetic film to be antiferromagnetically coupled to each other via an antiparallel coupling film, a non-magnetic intermediate layer, and a soft magnetic free layer.
