Ultralong, complexly structured micro- and nanoscale metallic glasses and fibers

The present invention and its embodiments propose a simple, unique, and scalable method for producing extremely long, highly uniform, and well-ordered micro- and nanoscale metallic glasses via thermal drawing the method comprising at least the steps of preparing a macroscopic scale first preform assembled from compatible materials for co-drawing such as a metallic glass structure encased in a supporting first cladding made of a polymer or glass; thermally drawing the first preform into a first fiber.
