1. A structure, comprising:

  • at least one tunnel barrier selected from the group of tunnel barriers consisting of MgO and Mg—

    ZnO; and

    an amorphous magnetic layer that includes Co and at least one additional element selected to make the layer amorphous, wherein the amorphous layer is in proximity with the tunnel barrier, thereby permitting spin-polarized current to pass between the tunnel barrier and the magnetic layer.
