Observation of magnetically induced polarization in a ferrofluid

Chain formation in low density dipolar hard spheres: A Monte Carlo study

“…Ferrofluids are colloidal suspensions of magnetic particles (50-100 A) in various carrier liquids [7]. At low temperatures ferrofluids are known to aggregate to form chains [8] although this requires the presence of an external magnetic field. Our results seem to indicate that such formation could be spontaneous for adequate values of the magnetic moments of the particles.…”

Electrical resistivity of magnetic fluids

“…The results of numerical simulations as well as of actual experimental results under the effect of, magnetic fields or the dipole-dipole interactions, reveal that there exist chain -like structures of magnetic particles which play an important role in physical phenomena observed in the MFs such as magnetomechanical, magneto-optical and magnetic properties of MFs [8][9][10][11][12].…”

“…Although the magnetic, magneto-optical, rheological properties of MFs have been studied extensively using different techniques [1][2][3][12][13][14]. the electrical behavior of MFs have been reported to a much lesser extent.…”

Exact Solution for a Chainlike Cluster Growth Model

“…Therefore, in this disordered spin system, similar to the previous carbon gas case, the clusterization process is governed firstly by short-range conditions [24] and secondly by the thermal excitation acting as an external bond breaking process. Studies of the liquid-gas transition [26] in systems of hard dipolar spheres [10], with application in ferrofluids [27], phase transitions [26] also show similar clusterization effects at high T and low density, governed by the same short-range conditions and an external bond cutting energy [10,28]. It is evident that the short-range conditions are generic to all disordered systems, in which few component chainlike clusters are dominant.…”
