Structure factor of the ferrofluid with chain aggregates: influence of an external magnetic field — •Elena Pyanzina1, Sofia Kantorovich1,2, Juan Cerda2, and Christian Holm21Ural State University, Ekaterinburg, Russia — 2ICP, University of Stuttgart, Stuttgart, Germany

We analyze the structure factor of a ferrofluid with strong interparticle magnetic dipole-dipole interaction. Results on mono- and bidisperse model systems in the presence of an external magnetic field are presented. The theoretical calculations are based on the explicit construction of radial distribution functions from the chain distributions obtained via density functional minimization. Data obtained via molecular dynamics simulations for the same model are provided for the verification of our analytical calculations.
