1. An apparatus for physical-vapor deposition of a multi-layer material structure onto a substrate, the material structure having plural layers deposited according to a predetermined sequence, each layer comprised of one of plural materials, the apparatus comprising:

  • a single, contiguous vacuum chamber;

    plural targets disposed in the vacuum chamber, at least one target comprised of one of the plural materials;

    at least one power source associated with the plural targets for supporting physical-vapor deposition;

    a substrate support chuck disposed in the vacuum chamber for supporting the substrate;

    an electromagnet coupled to the substrate support chuck, the electromagnet for formation of a magnetic field proximate to the substrate; and

    a mechanical indexing mechanism that moves the substrate support chuck and electromagnet relative to the plural targets in order to align and maintain the substrate in substantial alignment with any one of the targets to deposit the multi-layer material structure of the plural materials according to the predetermined sequence;

    the electromagnet moving along with the substrate support chuck such that the electromagnet may support deposition of magnetic materials onto the substrate at any of the plural targets.
