Abstract
We have considered the response of an ensemble of uniaxial ferromagnetic nanoparticles placed into a fluid to an alternating field in the presence of thermal bath. The attention was paid to the absorption of the field energy as a result of nanoparticles rotation in a viscous fluid. The influence of the inter-particle interaction effects was studied numerically based on the effective Langevin equation. Using the Barnes-Hut algorithm and CUDA technology, the set of numerical results, which describes the frequency dependence of the power loss, has obtained for various system parameters.
