1. A magnetic element, comprising:

  • (a) a first seed layer consisting of one or more of Ta, Zr, Nb, TaN, ZrN, NbN, and Ru;

    (b) a second seed layer contacting a top surface of the first seed layer and consisting of one or more of Mg, Sr, MgZr, and MgNb, the second seed layer forms a first interface with a magnetic layer;

    (c) the magnetic layer; and

    (d) a tunnel barrier layer comprised of MgO or another oxide that is formed on the magnetic layer to give a composite seed layer/magnetic layer/tunnel barrier layer configuration.
