Hysteretic Excitation in Non-collinear Antiferromagnetic Spin-Torque Oscillators: A Terminal Velocity Motion Perspective
Hao-Hsuan Chen, Ching-Ming Lee
We present a theoretical framework for non-collinear antiferromagnetic spin torque oscillators (NC-AFM STO) by unifying spin dynamics under the Poisson Bracket formalism. Shifting…
Terminal Velocity Motion Model Used to Analyze the Mutual Phase-locking of STNOs
Hao-Hsuan Chen, Ching-Ming Lee, Ching-Ray Chang
Using Legendre transformation, a standard theoretical approach extensively used in classical mechanics as well as thermal dynamics, two-dimensional non-linear auto-oscillators incl…
Hysteretic Mutual Synchronization of PERP-STNO Pairs Analyzed by a Generalized Pendulum-like Model
Hao-Hsuan Chen, Ching-Ming Lee, Lang Zeng +2
At present, the Kuramoto model is the standard and widely accepted theoretical approach for analyzing the synchronization of spin-torque nano-oscillators (STNOs) coupled by an inte…
Frequency Modulation and Voltage Locking of the Voltage Controlled Spin Oscillators (VCSOs)
Lang Zeng, Hao-Hsuan Chen, Deming Zhang +4
The oscillating frequency of typical Spin Torque Nano Oscillators (STNOs) can be modulated by injected DC current or bias magnetic field. And phase locking of STNOs to an external…
