摘要： A magnetic sensor includes: a magnetoresistive effect element having a sensitivity axis in a specific direction in which a fixed magnetic layer, a nonmagnetic material layer, and a free magnetic layer are laminated in this order; an antiferromagnetic layer which generates an exchange coupling bias with the free magnetic layer and which aligns the magnetization direction thereof in a predetermined direction provided on the free magnetic layer; and a ferromagnetic layer which generates an exchange coupling bias with the antiferromagnetic layer and which aligns the magnetization direction thereof in a predetermined direction provided on the antiferromagnetic layer. The magnetization direction on the exchange coupling bias in the free magnetic layer is the same direction as that on the exchange coupling bias in the ferromagnetic layer, and the ferromagnetic layer is able to impart a reflux magnetic field having a component along a sensitivity axis to the free magnetic layer.

摘要： In one embodiment, a TMR field sensor utilizes existing one or more self-test current lines in a configuration to extend magnetic field measurement range without sacrificing measurement sensitivity. The self-test current lines are energized to facilitate magnetic field measurement when the measured magnetic field reaches a threshold. The magnetic field created by self-test coil opposes an external magnetic field being measured to keep the net magnetic field within a desired range where the magnetic field sensor has linear output and desired sensitivity.

摘要： In a magnetic detection apparatus that prevents the output waveform from deviating regardless of whether two magneto-resistance elements are displaced relative to a magnet or accurately disposed relative to the magnet, the above two magneto-resistance elements are angled in consideration of a change in the direction of application of the magnetic field during displacement of the positional relationship and the anisotropy of the magneto-resistance elements so that the magneto-resistance elements are oriented in a direction in which the deviation of the output waveform caused by a change in the magnitude of application of the magnetic field during displacement of the positional relationship is cancelled, thereby preventing the detection accuracy of a magnetic moving body (detection target) being affected even if the magneto-resistance elements are displaced relative to the magnet due to manufacturing variations.

摘要： An electronic device may be provided with an electronic compass. The electronic compass may include magnetic sensors. The magnetic sensors may include thin-film magnetic sensor elements such as giant magnetoresistance sensor elements. Magnetic flux concentrators may be used to guide magnetic fields through the sensor elements. The magnetic flux concentrators may be configured to reduce the angular sensitivity of the magnetic sensors. A magnetic flux concentrator may be formed from multiple stacked layers of soft magnetic material separated by non-magnetic material. The non-magnetic material may have a thickness allows the magnetic layers to magnetically couple through the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction.

摘要： 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.
