Dynamics of Two Coupled Antiferromagnetic Terahertz-Frequency Josephson-Like Oscillators Driven by a Spin Current
We analyze magnetization dynamics in a system of two coupled THz-frequency Josephson-like spin Hall oscillators based on a layered structure consisting of a current-driven platinum layer and a layer of an antiferromagnet with easy-plane anisotropy. The THz-frequency signal from the antiferromagnet is received through the inverse spin-Hall effect in the platinum layer and we show that it can be used for the mutual coupling of two spin Hall oscillators leading to the improvement of the overall device performance.
