A method of generating electromagnetic radiation in the terahertz frequency range is disclosed herein. In one embodiment, the method comprises the steps of providing a bi-layer heterojunction comprising a ferromagnetic metal layer adjacent a non-magnetic metal layer, wherein the non-magnetic layer comprises one of platinum or tungsten and applying a femtosecond laser beam to the heterojunction. The terahertz electromagnetic radiation may be generated by an inverse spin orbit interaction comprising an inverse spin Hall effect and/or inverse spin orbital torques. A terahertz emitter device and an apparatus for generating electromagnetic radiation in the terahertz frequency range are also described.
