Active Control of Spin Waves in YIG-based Magnonics

  • Qin, Huajun (Principal investigator)

Project Details


Now that Moore's scaling law for semiconductor microprocessors is about to end, the research field for new computing technologies is wide open for disruptive ideas. Logic device concepts based on magnetic spin waves (magnons) are a promising contender. Spin waves are collective spin excitations in magnetic materials with macroscopic coherence lengths and wavelengths down to sub-100 nanometers. In C-WAVES, I will explore active manipulation of spin waves in thin films of the most promising material, ferrimagnetic yttrium iron garnet. Three control mechanisms are considered; (1) magnetic fields, (2) lasers, and (3) electric fields. The results of this project are relevant for the development of low-power parallel computing devices.
