Classification: CPC H  G | IPC G  H

Claim 0:
1. A thin film heterostructure material, the material comprising:
a crystalline ordered topological insulator sputter deposited on a substrate comprising an amorphous material;
an adjacent ferromagnetic material;
the topological insulator being configured to provide spin-orbit torque to the ferromagnetic material sufficient to produce at least one of resonant excitation and switching of magnetization in the ferromagnetic material; and
a distinct interfacial layer of diffused material from the ferromagnetic material in the topological insulator, at an interface of the topological insulator and the ferromagnetic material, the distinct interfacial layer configured to prevent diffusion of material from the ferromagnetic material into the topological insulator towards the substrate.
