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…
Highly efficient room temperature spin injection in a metal-insulator-semiconductor light emitting diode
P. Van Dorpe, V. F. Motsnyi, M. Nijboer +6
We demonstrate highly efficient spin injection at low and room temperature in an AlGaAs/GaAs semiconductor heterostructure from a CoFe/AlOx tunnel spin injector. We use a double-st…
Electrical Spin Injection in a Ferromagnetic / Tunnel Barrier/ Semiconductor Heterostructure
V. F. Motsnyi, V. I. Safarov, J. De Boeck +4
We demonstrate experimentally the electrical ballistic electron spin injection from a ferromagnetic metal / tunnel barrier contact into a semiconductor III-V heterostructure. We in…
