Abstract |
We study, both analytically and numerically, the phenomenon of energy dissipation in single-domain
ferromagnetic nanoparticles driven by an alternating magnetic field. Our interest is focused on the power loss
resulting from the Landau-Lifshitz-Gilbert equation, which describes the precessional motion of the nanoparticle
magnetic moment. We determine the power loss as a function of the field amplitude and frequency and analyze
its dependence on different regimes of forced precession induced by circularly and linearly polarized magnetic
fields. The conditions to maximize the nanoparticle heating are also analyzed. |
