Abstract: A magnetic sensor includes an MR element and two bias magnetic field generation units. The two bias magnetic field generation units are spaced apart from each other along a first direction and configured to cooperate with each other to generate a bias magnetic field. Each bias magnetic field generation unit includes a ferromagnetic layer and an antiferromagnetic layer stacked along a second direction orthogonal to the first direction. An element placement region is formed between the two bias magnetic field generation units when viewed in the second direction in an imaginary plane perpendicular to the second direction and intersecting the MR element. The element placement region includes a middle region and two end regions. The MR element is placed to lie within the middle region in the imaginary plane.

The magnetic property determination apparatus includes a magnetic detection unit that generates on the transport path a bias magnetic field having a magnetic field direction inclined to a transport surface of the paper sheet by a specific angle and detects the magnetic charge of the magnetic materials by detecting variation of the bias magnetic field; and a magnetization unit that is arranged upstream of the magnetic detection unit in the transport direction and magnetizes the magnetic materials by generating on the transport path a magnetization magnetic field having a magnetic field direction oriented in a direction different from the direction of the bias magnetic field. At a position at which the magnetic detection unit detects the magnetism, the magnetic materials are in a state in which the magnetic materials are magnetized in mutually different magnetization directions according to coercive force thereof.

Abstract: A method for determining of a position of an object using a sensor arrangement that includes a first magnetoresistive element and a second magnetoresistive element. A source provides a magnetic field with first and second magnetic poles. The source is arranged between the first magnetoresistive element and the second magnetoresistive element with the first magnetic pole facing the first magnetoresistive element and the second magnetic pole facing the second magnetoresistive element. The first magnetoresistive element is arranged in the magnetic field and provides a first output signal dependent on a position of the first magnetoresistive element relative to the magnetic field source. The second magnetoresistive element is arranged in the magnetic field and provides a second output signal dependent on a position of the second magnetoresistive element relative to the magnetic field source. A measurement unit determines a position of the magnetic field source relative to the first and the second magnetoresistive elements dependent on the first output signal and the second output signal.

Abstract: A first magnetoelectric conversion element group including magnetoelectric conversion elements, and a second magnetoelectric conversion element group including magnetoelectric conversion elements are arranged across a cutout of a wiring board. The first and second groups are arranged line-symmetrically with respect to a first imaginary line. The elements in the first and second groups are arranged line-symmetrically with respect to a second imaginary line. The first imaginary line and the second imaginary line orthogonally intersect each other at a placement position at which a current path to be measured is placed. The orientation of the sensitivity axis of each of a plurality of magnetoelectric-conversion-element sets having point symmetry about the placement position is parallel or antiparallel. An element spacing, which is spacing between neighboring elements in the first and second groups, is narrower than a group spacing, which is the narrowest spacing between the first and second groups.
