Signatures of Chaos in Thermal Switching of Nanomagnets
M. d'Aquino, C. Serpico, S. Perna +4
Thermally-activated magnetization dynamics of small nanoparticles subject to microwave (AC) external fields is studied. It is shown that, under sufficiently strong microwave excita…
Power Spectral Density of Magnetization Dynamics Driven by a Jump-Noise Process
A. Lee, G. Bertotti, C. Serpico +1
Random magnetization dynamics driven by a jump-noise process is reduced to stochastic magnetic energy dynamics on specific graphs using an averaging technique. An approach to analy…
Conservative effects in spin-transfer-driven magnetization dynamics
Giorgio Bertotti, Claudio Serpico, Isaak D. Mayergoyz
It is shown that under appropriate conditions spin-transfer-driven magnetization dynamics in a single-domain nanomagnet is conservative in nature and admits a specific integral of…
Spin-wave instabilities in spin-transfer-driven magnetization dynamics
G. Bertotti, R. Bonin, M. d'Aquino +2
We study the stability of magnetization precessions induced in spin-transfer devices by the injection of spin-polarized electric currents. Instability conditions are derived by int…
