Investigation of the effective field in magnetic fluids
The authors describe investigations of the effective field caused by the orientational interaction between ferroparticles for magnetic fluids with a conducting and a nonconducting base. The magnetic susceptibility of four magnetic fluid specimens was investigated. Specimens consisted of a colloid solution of magnetite in kerosene, stabilized with oleic acid; mercury-based magnetic fluids, a colloid solution of finely dispersed iron particles in mercury, a solution of iron particles with a lower degree of dispersion, and a solution of cobalt particles. Figures show the temperature dependences of the magnetic suceptibility of the fluid specimens. It was shown that under certain conditions, it is possible that instabilities can arise and heterophase impurities can form in accordance with the mechanism proposed previously in both electrically conducting and nonconducting magnetic fluids.
