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…
Quantized spin wave modes in magnetic tunnel junction nanopillars
A. Helmer, S. Cornelissen, T. Devolder +4
We present an experimental and theoretical study of the magnetic field dependence of the mode frequency of thermally excited spin waves in rectangular shaped nanopillars of lateral…
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…
Auto-oscillation threshold and line narrowing in MgO-based spin-torque oscillators
S. Cornelissen, L. Bianchini, G. Hrkac +7
We present an experimental study of the power spectrum of current-driven magnetization oscillations in MgO tunnel junctions under low bias. We find the existence of narrow spectral…
