Abstract
A method for manufacturing a self-biased circulator includes cooling a nanocomposite material to a magnetization temperature below 200 K, applying an external magnetic field to the nanocomposite material to form a magnetic nanocomposite material, providing the magnetic nanocomposite material in a semiconductor substrate, and providing one or more metal layers over the magnetic nanocomposite material to form a circulator. By cooling and then magnetizing the nanocomposite material, a performance of the circulator may be significantly improved.
