Zusammenfassung

We examine binary mixtures of superparamagnetic colloidal particles confined to a two-dimensional water air interface both by real-space experiments and Monte Carlo computer simulations at high coupling strength. In the simulations, the interaction is modelled as a pairwise dipole dipole repulsion. While the ratio of magnetic dipole moments is fixed, the interaction strength governed by the external magnetic field and the relative composition is varied. Excellent agreement between simulation and experiment is found for the partial pair distribution functions including the fine structure of the neighbour shells at high coupling. Furthermore local crystal nuclei in the melt are identified by bond-orientational order parameters and their contribution to the pair structure is discussed.
