Abstract
Series of dilutions of a kerosene-based magnetic fluid with magnetite particles stabilized with oleic acid is employed to study the colloidal stability of the magnetic fluid, using magnetization curve measurements. Analyzing the dependence of the mean magnetic diameter of particles on their volume fraction in the magnetic fluid, information regarding the colloidal stabilization of particles within magnetic fluid is obtained. The result of the analysis is supported by the magneto-optic investigations of the magnetic fluid.
