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…
Comment on "Compositional and Microchemical Evidence of Piezonuclear Fission Reactions in Rock Specimens Subjected to Compression Tests" [Strain 47 (Suppl. 2), 282 (2011)]
G. Amato, G. Bertotti, O. Bottauscio +6
It is shown that the chemical composition data published by Carpinteri et al. in the article "Compositional and Microchemical Evidence of Piezonuclear Fission Reactions in Rock Spe…
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…
Study of the connection between hysteresis and thermal relaxation in magnetic materials
Vittorio Basso, Cinzia Beatrice, Martino LoBue +2
The connection between hysteresis and thermal relaxation in magnetic materials is studied from both the experimental and the theoretical viewpoint. Hysteresis and viscosity effects…
Stochastic Dynamics in Quenched-in Disorder and Hysteresis
Giorgio Bertotti, Vittorio Basso, Alessandro Magni
The conditions under which relaxation dynamics in the presence of quenched-in disorder lead to rate-independent hysteresis are discussed. The calculation of average hysteresis bran…
