The theme vision is to develop new materials for the processing of information using spin waves and to integrate these materials into heterostructures for generating, transmitting, and detecting spin waves in prototypical devices. The ideal spin wave material should have low loss, an anisotropy that can be engineered through interfacial and bulk electronic structure, and it must be integrated with a high-bandwidth source and detector. The first task of the theme will advance the state-of-the-art by synthesizing new classes of spin wave materials based on magnetic garnets and Heusler alloys. Their properties in both films and nanostructures will be optimized through a program of structural and magnetic characterization, microwave measurements, and theory and simulation. New approaches to high-frequency operation with low loss will be pursued, including spin wave channels based on antiferromagnetic materials. In the second task, the theme will pursue new heterostructures for integrating spin wave materials into devices. This will include implementing spin wave generators and detectors using spin-orbit torque as well as a higher risk but potentially high payoff approach in which magneto-electric or magneto-elastic coupling are used for generation and detection.
