Direct calculation of the attempt frequency of magnetic structures using the finite element method
G. Fiedler, J. Fidler, J. Lee +4
A numerical implementation of the transition state theory (TST) is presented which can be used to calculate the attempt frequency of arbitrary shaped magnetic nanostructure…
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…
Internal effective field sources for spin torque nano pillar oscillators
Gino Hrkac, Thomas Schrefl, Julian Dean +4
In this paper we numerically conduct micromagnetic modelling with an expended micromagnetic model that includes the spin torque term and an impedance model to investigate methods t…
Mutual phase-locking in high frequency microwave nanooscillators as function of field angle
G. Hrkac, T. Schrefl, S. Bance +4
We perform a qualitative analysis of phase locking in a double point-contact spinvalve system by solving the Landau-Lifshitz-Gilbert-Slonzewski equation using a hybrid-finite-eleme…
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…
