Abstract

Ferrofluids are colloidal suspensions of magnetic particles which we model as a dilute gas of dipolar hard spheres. At low particle density the osmotic pressure and magnetic susceptibility may be expanded in a virial series. We evaluate the second virial coefficients for fluids confined to a line, or to a plane, as well as ordinary three dimensional fluids in ellipsoidal containers. We focus our attention on anisotropy of the magnetic susceptibility and point out the role of particle chaining in determining the magnetic anisotropy of low dimensional ferrofluids.

We convert to an approximate hard sphere potential with a = 2σ. The Boyle temperature (we use TB = 1853°K for H20 and TB = 3638° K for CHC13 ) is the zero of the second virial coefficient calculated from the Stockmayer potential.Google Scholar
