Abstract

In this paper, the initial susceptibility of epsilon-Fe3N magnetic fluid at volume concentrations in the range Phi = 0.0 similar to 0.0446 are measured. Compared with the experimental initial susceptibility, the Langevin, Weiss and Onsager susceptibility were calculated using the data obtained from the low concentration epsilon-Fe3N magnetic fluid samples. The viscosity of the epsilon-Fe3N magnetic fluid at the same concentrations is measured. The result shows that, the initial susceptibility of the low concentration e-Fe3N magnetic fluid is proportional to the concentration. A linear relationship between relative viscosity and the volume fraction is observed when the concentration Phi < 0.02.
