Ultrafast terahertz detectors based on three-dimensional meta-atoms
B. Paulillo, S. Pirotta, H. Nong +8
Terahertz (THz) and sub-THz frequency emitter and detector technologies are receiving increasing attention, underpinned by emerging applications in ultra-fast THz physics, frequenc…
Frequency shift keying in vortex-based spin torque oscillators
M. Manfrini, T. Devolder, Joo-Von Kim +4
Vortex-based spin-torque oscillators can be made from extended spin valves connected to an electrical nanocontact. We study the implementation of frequency shift keying modulation…
Auto-oscillation threshold, narrow spectral lines, and line jitter in spin-torque oscillators based on MgO magnetic tunnel junctions
T. Devolder, S. Cornelissen, L. Bianchini +5
We demonstrate spin torque induced auto-oscillation in MgO-based magnetic tunnel junctions. At the generation threshold, we observe a strong line narrowing down to 6 MHz at 300K an…
Current-driven vortex oscillations in metallic nanocontacts
Q. Mistral, M. van Kampen, G. Hrkac +6
We present experimental evidence of sub-GHz spin-transfer oscillations in metallic nano-contacts that are due to the translational motion of a magnetic vortex. The vortex is shown…
