摘要：

A mean field theory describing the magnetic properties of ferrofluids with interacting particles has been derived. The theory explains the previously observed Curie-Weiss behavior of ferrofluids, and a superferromagnetic ordering below a critical temperature is predicted. As an example we consider a ferrofluid which consists of a suspension of magnetite particles with a diameter of 8 nm. The particles are coated with a 2 nm thick layer of surfactant molecules.
