1. A method for manufacturing a thin-film magnetic device, including:

  • providing a substrate having a surface characterized by first and second axes that are perpendicular to each other;

    applying to the surface of the substrate a magnetic field oriented parallel to the first axis;

    growing a relatively thin thin-film layer of magnetic material on the substrate in the presence of the magnetic field to a thickness sufficiently thick that the layer exhibits magnetic properties that are substantially independent of surface effects, but sufficiently thin that the easy axis of magnetization of the material is oriented parallel to the second axis.
