  • Magnetoresistive sensor
    Patent number: 10718830
    Abstract: A magnetoresistive sensor is provided. The magnetoresistive sensor comprises a magnetic sensing layer, a magnetic reference layer, and a tunnel barrier layer between the magnetic sensing layer and the magnetic reference layer. The magnetoresistive sensor also comprises a sensing exchange layer having a layer of anti-ferromagnetic material. The sensing exchange layer is exchange coupled with the magnetic sensing layer. Also, the magnetoresistive sensor still further comprises a reference exchange layer having a layer of anti-ferromagnetic material. The reference exchange layer is exchange coupled with the magnetic reference layer.
