Magnetization of ferrofluids with dipolar interactions - a Born--Mayer expansion
arXiv:cond-mat/0005204 · doi:10.1103/PhysRevE.62.6875
Abstract
For ferrofluids that are described by a system of hard spheres interacting via dipolar forces we evaluate the magnetization as a function of the internal magnetic field with a Born--Mayer technique and an expansion in the dipolar coupling strength. Two different approximations are presented for the magnetization considering different contributions to a series expansion in terms of the volume fraction of the particles and the dipolar coupling strength.
