摘要
The idea to establish coherent relaxation in an assembly of magnetic moments by placing it inside a passive resonator is applied to the case of single-domain ferromagnetic nanoparticles. The dynamics of magnetization inversion of a nanoparticle is governed by the Landau-Lifshitz (spin-lattice) relaxation and radiation damping. The numeric simulations enable us to account for the interparticle dipole-dipole interactions in a rigorous way. A new mechanism of fast relaxation in a nanoparticle assembly is suggested and described.
