Spin-wave emission with current-controlled frequency by a PMA-based spin-Hall oscillator

This is a pure research paper with zero GitHub presence (0 stars, 7 forks but no active repo indicated). The project demonstrates a novel material stack (Ga:YIG) and operational regime (PMA-based SHO) for spin-wave generation, combining established spin-Hall oscillator physics with perpendicular anisotropy engineering. The novelty lies in the specific combination of material choice and magnetic configuration to improve efficiency and frequency control in neuromorphic applications, not in fundamental new physics. Defensibility is extremely low because: (1) this is a proof-of-concept paper with no software artifact or reproducible codebase; (2) the contribution is primarily experimental physics, not a generalizable tool; (3) there are no users, integration pathways, or ecosystem effects; (4) frontier labs (Google, IBM) actively research neuromorphic computing and spin-wave devices, making this incremental academic work. Frontier risk is low only because the work is too specialized and hardware-dependent for direct competition—it's a niche materials science experiment, not a software platform or widely-deployable algorithm. If this were productized into a hardware module or control software, frontier risk would escalate to medium-high. The 129-day age with zero velocity indicates this is a static paper artifact with no ongoing development.
