APDE seminar @BCAM: Self-organisation of magnetic nanoparticles in a viscous fluid via dipolar interactions

Abstract

The purpose of this talk is to present recent investigations for the dynamics of an ensemble of monodomain magnetic nanoparticles suspended in a viscous fluid. The particles interact via dipolar magnetic forces, with their magnetic moments constrained along their individual easy axes of magnetization. The physical model incorporates particle inertia, viscous drag exerted by the fluid, and a repulsive interaction to account for collisions and prevent overlap. This talk presents both numerical investigations on the dynamics of the particles and some theoretical results on the steady states.
