Citation Energy dissipation in single-domain ferromagnetic nanoparticles: Dynamical approach / T.V. Lyutyy, S.I. Denisov, A.Yu. Peletskyi, C. Binns // Physical Review B. - 2015. - Vol. 91. - P. 054425.
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.
