ABSTRACT:
A magnetic sensor includes a sensor stack having a sensing layer. A first biasing structure having a first magnetization vector is positioned adjacent to the sensor stack to produce a biasing field that biases the sensing layer. A second biasing structure having a second magnetization vector is positioned within the sensor stack relative to the sensing layer to counter the biasing field at a center of the sensing layer.
