TL;DR: In this paper, a general analytic approach to the theory of microwave generation in magnetic nano-structures driven by spin-polarized current was proposed. But the proposed approach is based on the universal model of an auto-oscillator with negative damping and nonlinear frequency shift.

TL;DR: This work demonstrates the generation of single-mode coherent auto-oscillations in a device that combines local injection of a pure spin current with enhanced spin-wave radiation losses, and suggests a new route for the implementation of nanoscale microwave sources for next-generation integrated electronics.

TL;DR: In this paper, the authors demonstrate that a bi-layer of a heavy metal (Pt) and a Bi-axial antiferromagnetic (AFM) dielectric (NiO) can be a source of a coherent THz signal.

TL;DR: It is demonstrated that two distinct spin wave modes can be excited, with different frequency, threshold currents, and frequency tunability, and one mode is identified as an exchange-dominated propagating spin wave, and the other as a self-localized nonlinear spin wave bullet.

TL;DR: The results show that these nano-oscillators driven by pure spin current generated via the spin Hall effect can be efficiently synchronized by applying a microwave signal at approximately twice the frequency of the auto-oscillation, which opens additional possibilities for the development of novel spintronic devices.
