Self-assembled hexagonal double fishnets as negative index materials
Kristof Lodewijks, Niels Verellen, Willem Van Roy +2
We show experimentally the successful use of colloidal lithography for the fabrication of negative index metamaterials in the near-infrared wavelength range. In particular, we inve…
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…
Direct experimental measurement of phase-amplitude coupling in spin torque oscillators
L. Bianchini, S. Cornelissen, Joo-Von Kim +4
We study spin-torque induced oscillations of MgO magnetic tunnel junctions in the time domain. By using the Hilbert transform on the time traces, we obtain for the first time a dir…
