Organization of Colloids in Ferrofluids — •Ayan Ray and Thomas Fischer — Universität Bayreuth, 95440 Bayreuth, Germany

Colloidal particles (magnetic and non-magnetic) are the basic building blocks of complex structures with unique optical properties. When these mono-disperse particles with controlled shape, size, volume, and concentration are dispersed in a ferrofluid in a static magnetic field they self-assemble into symmetric arrangements. Here we try to demonstrate the dynamical behavior of a mixture of paramagnetic and non magnetic colloidal particles in a ferrofluid under the influence of a rotating magnetic field.
