Binary mixtures of magnetic fluids
Physical Review E, 2003We study a binary mixture of a van der Waals fluid and a ferromagnetic fluid at zero magnetic field on the basis of the mean field Ising fluid model and the van der Waals theory with quadratic mixing rules. Depending on three reduced parameters, the phase diagram shows a surface of magnetic phase transitions and lines of tricritical points, critical ...

Convective instability of magnetic fluids
Physical Review E, 2004A theoretical investigation of the convective instability problem in the thin horizontal layer of a magnetic fluid heated from below is carried out. The effects of the relaxation time tau and the vortex (rotational) viscosity xi are considered and discussed.

NMR-Characterization of Magnetic Fluids
Zeitschrift für Physikalische Chemie, 2006Summary 31P-NMR spectra have been measured on aqueous solutions and gels of phosphorylated polyvinyl alcohol in absence and in presence of dispersed magnetic nanoparticles. In this system, the rotational diffusion is still rapid enough for a sufficient averaging of the CSA tensor of the 31P nucleus.

The impact between a magnetic fluid drop and a magnetic fluid surface
Journal of Magnetism and Magnetic Materials, 2002This paper deals with the experimental investigation of the impact between a magnetic fluid drop and a surface of the same magnetic fluid in the uniform magnetic field normal and tangential to the surface. Impact phases and propagation of waves are studied and their characteristics as a function of a magnetic field are determined.

Magnetic Fields for Fluid Motion
Analytical Chemistry, 2010Three forces induced by magnetic fields offer unique control of fluid motion and new opportunities in microfluidics. This article describes magnetoconvective phenomena in terms of the theory and controversy, tuning by redox processes at electrodes, early-stage applications in analytical chemistry, mature applications in disciplines far afield, and ...

Wave Structures in Magnetic Fluid
International Journal of Fluid Mechanics Research, 2003The authors investigate conditions for onset and stability of wave structures in magnetic fluids with changing microstructure. Three types of magnetic fluids are examined: fluids which are unstable in any magnetic fields, and fluids for which one or two asymptotically stable states exist.

Sensors Based on Magnetic Fluids
2013Magnetic fluids are materials that can be successful used in sensors and actuators as the active mass. Due to their intrinsic nature, magnetic fluids can be manipulated and controlled by suitable magnetic field which can modify their physical properties such as density and viscosity.

Wave propagation in magnetic fluids
Physical Review A, 1987This paper deals within the relativistic framework with the wave propagation in magnetizable fluids, assumed to be perfect, magnetically soft, isotropic, and inhomogeneous with an arbitrary isotropic law \ensuremath{\chi}=\ensuremath{\chi}(T,r,\ensuremath{\Vert}b${\ensuremath{\Vert}}^{2}$) (\ensuremath{\chi},T,r,\ensuremath{\Vert}b\ensuremath{\Vert ...
