Structural transformations in ferrofluids
Physical Review E, 2003We present results of theoretical study of internal structural transformations in magnetic liquids consisting of identical spherical magnetic particles suspended in a carrier liquid. As the results show, when the dimensionless characteristic energy of magnetic interaction epsilon between particles is less than a certain critical value epsilon('), the ...

Anomalous diffusion in ferrofluids
Physical Review E, 2009By dynamic light scattering we have studied suspensions of ferrimagnetic maghemite (gamma-Fe2O3) nanoparticles in n -decane with attractive interparticle interaction. The measurements in the suspensions of different concentrations ranging from 0.21 to 25.8 wt % have been compared in zero external field and in the magnetic field of 270 mT.

Capillary viscosimetry on ferrofluids
Journal of Physics: Condensed Matter, 2008Experiments performed for different ferrofluids under shear flow have shown that an increase of the magnetic field strength applied to the sample yields an increase of the fluid's viscosity, the so called magnetoviscous effect. It has been shown that the magnitude of the effect is strongly related to the modification of the microstructure of ...

Adhesion phenomena in ferrofluids
Physical Review E, 2004One efficient way of determining the bond strength of adhesives is to measure the force or the work required to separate two surfaces bonded by a thin adhesive film. We consider the case in which the thin film is not a conventional adhesive material but a high viscosity ferrofluid confined between two narrowly spaced parallel flat plates subjected to ...

La Radiologia medica, 1987
Ferrofluids are colloidal suspensions of extremely small ferromagnetic particles, the physical properties of which belong to a very complex chapter of modern magnetohydro-dynamics. Because of that, ferrofluids will possibly open new perspectives of medical applications, both in diagnostic radiology and therapeutic oncology.

Since the first preparation of ferrofluids in the mids of the 60s the understanding of their behavior is a matter of both theoretical and experimental research. Especially the interaction of rheological and magnetic properties (known as the magnetoviscous effect) is a main concern for being the source of the unique behavior of ferrofluids.
