Structure formation in ferrofluid monolayers-I: Simulations. — •Juan J. Cerda1, Sofia Kantorovich2,3, and Christian Holm1,2 — 1FIAS, Frankfurt am Main, Germany — 2MPI-P, Mainz, Germany — 3Ural State Univ., Ekaterinburg, Russia
Molecular dynamics (MD) is used to study thoroughly the microstructure formation of monodisperse and bidisperse ferrofluid monolayers. Long-range dipolar interactions are computed using a recently developed dipolar-P3M-layer correction algorithm. In comparison to the traditional Ewald sum methods, this approach allows to handle and characterize larger systems. An extensive comparison with theoretical density functional theory, and experimental results from in situ cryogenic tansmission electron microscopy [Klokkenburg et al., PRL 97,185702,(2006)] will be also presented.
