Abstract
Disclosed herein are layered Heusler alloys. The layered Heusler alloys can comprise a first layer comprising a first Heusler alloy with a face-centered cubic (fcc) crystal structure and a second layer comprising a second Heusler alloy with a fcc crystal structure, the second Heusler alloy being different than the first Heusler alloy, wherein the first layer and the second layer are layered along a layering direction, the layering direction being the [110] or [111] direction of the fcc crystal structure, thereby forming the layered Heusler alloy.
Claims18
A layered Heusler alloy, comprising:
- a first layer comprising a first Heusler alloy with a face-centered cubic (fcc) crystal structure;
- a second layer comprising a second Heusler alloy with a fcc crystal structure, the second Heusler alloy being different than the first Heusler alloy;
- wherein the first layer and the second layer are layered along a layering direction, the layering direction being the [110] or [111] direction of the fcc crystal structure, thereby forming the layered Heusler alloy;
- wherein the layered Heusler alloy has a magnetocrystalline anisotropy of greater than 0 J/m3 along a direction perpendicular to the layering direction;
- wherein the layered Heusler alloy comprises a half metal or a near half metal;
- and
- wherein the layered Heusler alloy has a Fermi level and a gapped spin-channel with a gap, and wherein the Fermi level of the layered Heusler alloy falls within the gap of the gapped spin-channel of the layered Heusler alloy.
