Here, we study the MF-directed assembly in binary colloids made up of strong ferromagnetic and diamagnetic microparticles dispersed in ferrofluids. We present observations of the aggregation of pairs and small groups of particles to build equilibrium assemblies. We also develop a theoretical model capable of solving the aggregation dynamics and predicting the particle trajectories, a key factor to understand the physics governing the MF-directed assembly.}, organization = {The project MINECO FIS2013-41821-R (Spain) is acknowledged for financial support.}, publisher = {Institute of Physics (IOP)}, keywords = {Dynamics of magnetic nanoparticles}, keywords = {Self-assembly}, keywords = {Colloids}, title = {Dynamics of magnetic assembly of binary colloidal structures}, doi = {10.1209/0295-5075/111/37002}, author = {Nogueras-Lara, Francisco and Rodríguez Arco, Laura and López López, Modesto Torcuato}, }
