Ground state structures in ferrofluid monolayers: Theory and Simulations. — •Sofia Kantorovich1,2, Victor Danilov1, Taisia Prokopyeva1, and Christian Holm2 — 1Ural State University, Ekaterinburg, Russia — 2University of Stuttgart, Stuttgart, Germany
The investigation of the microstructure of ferrofluid monolayers at low temperatures was extended to bidisperse model systems. Previously we have shown that a single ideal ring is the most probable ground state structure for a monodisperse ferrofluid monolayer. Starting with system containing large particles we introduce small particles as defects, and analyze the resulting structures, using a combination of analytical methods and Monte Carlo simulations. The crucial influence of the interaction between particles from different fractions (namely, large and small ones) is demonstrated.
