“…One simple approximation is the so-called randomphase approximation. As shown in many previous works, [17][18][19][20] the random-phase approximation cannot provide a realistic description for the dipolar system. Teixeira and Telo da Gama 17 proposed a MMF approximation which is based on a low-density expression for the radial distribution function.…”

“…Using the MMF density-functional theory Talanquer and Oxtoby 19 studied the vapor-liquid nucleation of the Stockmayer fluid. To investigate the interfacial properties of strongly dipolar fluids, Frodl and Dietrich 20,21 developed a more sophisticated density-functional approach without using the expansion of the grand canonical potential. They showed that when the reduced dipole moment is less than 1 ͑weakly dipolar͒, the MMF theory 17 gives reasonably good results compared to their theory ͑e.g., the discrepancy in the critical temperature is less than 10%͒.…”

In the framework of modified mean-field density-functional theory, effects of a uniform electric field on the interfacial properties of a model dipolar fluid ͓Teixeira and Telo da Gama, J. Phys.: Condens. Matter 3, 111 ͑1991͔͒ are studied. Both density and orientational order-parameter profiles of the planar vapor-liquid interface are obtained as a function of the field strength. For the dipolar fluids with reduced dipole moment 0 *р1, we find that the field ͑under the condition 0 *E*/T*Ӷ1͒ can shift the surface tension by few percent. We also find that the electric field actually reduces the thermodynamical surface tension but enhances the mechanical surface tension at the equimolar dividing surface. To detect these field effects on the surface tension we estimate the field strength which can be as high as 10 8 V/m.

We review equilibrium thermodynamic properties of systems of magnetic particles like ferrofluids in which dipolar interactions play an important role. The review is focussed on two subjects: (i) the magnetization with the initial magnetic susceptibility as a special case and (ii) the phase transition behavior. Here the condensation ("gas/liquid") transition in the subsystem of the suspended particles is treated as well as the isotropic/ferromagnetic transition to a state with spontaneously generated long-range magnetic order.

“…The dipole-dipole interaction is strongly anisotropic and long-ranged, hence notoriously difficult to treat theoretically. For this reaeon, a number of authors [1][2][3][4][5] have sought to derive isotropic effective interaction potentials that nevertheless capture the essentials of the true dipolar fluid, for the purpose of easier computation of its phase behaviour. In all cases, the leading term of this effective potential is attractive and has the same distance dependence as, e.g., the long-range part of the Lennard-Jones (LJ) potential.…”
