My overall aim is to develop a Magnonic technology platform where Spintronic, Spin-Caloritronic and Nano-plasmonic devices and structures combine to create ground-breaking functionality from novel interactions between charge, spin, heat and light. With traditional Magnonic studies typically geared towards the low GHz range, and nanoplasmonic phenomena primarily focusing on visible light, my proposed platform will also attempt to bridge the so-called “THz gap” and create ultra-broadband and rapidly tuneable spin wave (SW) based signal generators, manipulators, detectors, and even spectrometers, in the 10–200 GHz frequency range. I will reach this goal by transferring my documented nano-contact spin torque oscillator (NC-STO) expertise into the magnonics world of both metal and insulator based SW propagation, add recently discovered spin hall (SHE) and inverse spin hall effect (ISHE) SW manipulation/detection, and combine it with my recently acquired know-how in nanoplasmonics.My specific aims are:1. SW generation and manipulation using metal and YIG based NC-STOs2. SW-light/heat interaction using nanoplasmonic structures and Spin-Caloritronics3. ISHE/SHE detection and control of propagating SWs in metals and YIG
