Abstract
A device comprising a first magnetic layer (e.g., CoMnSi Heusler alloy or a tetragonally distorted perpendicularly magnetized (PMA) Heusler alloy such as MnGa, MnGe, etc.) and a second magnetic layer (e.g., CoMnSi Heusler alloy or a tetragonally distorted perpendicularly magnetized (PMA) Heusler alloy such as MnGa, MnGe, etc.), and a metal halide tunnel barrier in between the first and second magnetic layers, wherein the metal halide tunnel barrier (e.g., NaF, NaCl, NaBr, LiF, LiCl, and LiBr or their combination) is lattice matched within a predetermined limit (e.g. 5%) of both the first and second magnetic layers.
