The theme vision is to develop mechanisms and heterostructures in which magnetic properties can be manipulated by the application of an electric field via a small gate voltage through controlled motion of an ionic species in solid-state devices. The goal is to dramatically advance the state-of-the-art in magneto-ionic control of magnetism, by achieving reliable low voltage, low energy, high endurance, and dynamic analog control over magnetic properties at room temperature and integrating this functionality into magnetic devices such as MTJs. This will enable magnetic logic devices in which a large dynamic range analog manipulation of the output is possible. Such devices will also be relevant for a variety of demonstration platforms, including proof-of-principle MTJ crossbars for neuromorphic computing. Key features of the theme effort include: (1) The use of active magnetic structures based on both magnetic metals and oxides; (2) The exploration of magneto-ionic concepts based on getter layers; (3) An emphasis on materials fundamentals to understand the mechanisms of magneto-ionic control and the fundamental limits on manipulation speed, durability, and generality; and (4) The development of platforms for device demonstrations in neuromorphic and stochastic computing.
