Controlling the Spectral Characteristics of a Spin-Current Auto-Oscillator with an Electric Field
We published a paper entitled “Controlling the Spectral Characteristics of a Spin-Current Auto-Oscillator with an Electric Field” in PR APPLIED [Physical Review Applied 8, 021001 (2017)]. In this work, we demonstrated that the characteristic currents required for the excitation, the intensity and the spectral characteristics of the generated magnetic nano-oscillation can be tuned by the gate voltage, and the effect of electrostatic gating becomes enhanced in the strongly nonlinear oscillation regime. Electric-field modulation of the current-induced magnetization oscillations and spin waves demonstrated in this work can be utilized for frequency mixing, synchronization, and in logic gates in spin wave-based electronic (magnonic) devices.

We focuses on experimental studies of magnetic nano-oscillator, spin wave excitation, and spin-transport phenomena in new functional materials and hybrid nanoscale structures such as MTJ, spin valve, spin Hall effect, SC/FM et al.
Currently research topics include:
- Spin current generation (Spin Hall and Rashba effects) in strong spin-orbit coupling materials
- Magnetic nano-oscillator and spin wave excitation by pure spin current
- Nontrivial magnetic texture (magnetic Vortex, Skyrmion, Meron) in magnetic thin films
- Electric-field control of ferromagnetism
- Spin transport in ferromagnetic and ferroelectric tunnel junctions
- Super-spintronics in superconductor and ferromagnet hybrid structures
