1. a linear thin-film magnetoresistive sensor is characterized in that, comprising:

  • Seed Layer;

    Reference layer is positioned on the described Seed Layer, has first magnetic moment;

    Non magnetic separation layer is positioned on the described reference layer, and reference layer and magnetic free layer are isolated;

    The magnetic free layer is positioned on the non magnetic separation layer, has second magnetic moment, and described second magnetic moment has the anisotropy perpendicular to face, and the direction of second magnetic moment is vertical mutually with the direction of first magnetic moment.
